It might be strange at first , but yes it is a real number under the principal branch. (i) (1 - i)x + (1 + i)y = 1 - 3i asked Aug 13 in Complex Numbers by Aryan01 ( 50.1k points) The value of is i. Step-by-step explanation: To find: The correct option to this question is = Because: i raised to an odd power is = i. i, i.e., iota is an imaginary number which is mathematically equals to √(-1) It has been proven that the powers of iota give the value plus or minus i. This page will show you how to do this. log (i) has a value of approximately 0.68i, which would give: x = i^i log (x) = i log (i) = i i*0.68 = -0.68 x = 10^ (-0.68) = approximately 0.2079. The square of an imaginary number bi is −b 2.For example, 5i is an imaginary number, and its square is −25.By definition, zero is considered to be both real and imaginary. So iⁱ = (e^(i(4k+1)π/2))ⁱ = e^(i²(4k+1)π/2) = e^(-(4k+1)π/2) for all Integers k. Some values of iⁱ (for k = -2 to 2) are: e^(7π/2) ≈ 59609.7 e^(3π/2) ≈ 111.318 e^(-π/2) ≈ 0.20788 e^(-5π/2) ≈ 0.000388203 e^(-9π/2) ≈ 0.000000724947 So there isn't one specific value of iⁱ, but yes, they are all Real values. It is not well-defined. I mean, we can take $5\pi/2$ and get a different answer? Increment i (i becomes 1) Assign the value of step 1 to i (i becomes 0) Not that the increment is being discarded. What is imaginary infinity, $i\lim\limits_{x \to \infty} x = i\infty$? However, what happens when $i^i$ is performed? It removes the element at position 5 from values 4. The imaginary unit number is used to express the complex numbers, where i is defined as imaginary or unit imaginary. Autodetect radians/degrees. (However, while the square roots of a number always have the same magnitude even if they differ in sign, the values of have different magnitudes). This would be the principal one, and if the problem asks for one, this is it. I have always seen everywhere $\arg (re^{i\theta})=\theta +2k\pi$ (when $r>0$ and $\theta\in\mathbb{R}$). @Argon I know that, but it is still true, the argument of $i$ is $\frac{\pi}{2}$. The same thing must be done in complex analysis with the log function. $$z^x := e^{x\log z }$$ -8 B. For example, $$i^i=(\cos(\pi/2)+i\sin(\pi/2))^i=e^{i(i\pi/2)}=e^{-\pi/2}$$, for any complex number $z\in \mathbb C$ it can be written as $z=x+iy$ or in the polar form $z=re^{i\theta}$ where $r=\sqrt{x^2+y^2}$ and $\theta=\arctan(\frac{y}{x})$, so in particular $i=0+i1$ which implies that $r=1$ and $\theta=\frac{\pi}{2}$ Thus, $$i=e^{\frac{\pi i}{2}}$$ which implies that $$i^i=(e^{\frac{\pi i}{2}})^i=e^{\frac{-\pi }{2}}.$$, site design / logo © 2021 Stack Exchange Inc; user contributions licensed under cc by-sa. You seem to say that $\arg i=\pi/2+2\pi ik$. How to incorporate scientific development into fantasy/sci-fi? Can this equation be solved with whole numbers? Under a different branch you'll get a different result. I understand that when you raise any number $x$ to a power, you multiply $x$ by itself the number of times indicated in the power. Important! Well, in the complex numbers you consider an exponential of a base other than $e$, such as $z^x$, to be: So we have: Use the following calculator to find the current value of an I bond. Well i is equal to the square root of -1 so i is a real number and it approx. e. the sentinel value. An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i 2 = −1. e^{-\pi/2}$is the principal value with$n=0$. So what's the right answer? If i is an imaginary number. Answer: Step-by-step explanation: Powers of The Imaginary Unit. The value of 'i' is just 'i'. i^i=e^(-pi/2) (multipling the exponent by i raises to the power of i .and i*i=-1. in first step (i++) value is incremented by one but original value 10is used. 2. Hi, Since sine and cosine are periodic with period 2 π, for any integer n . Hi again Wayne If you use the complex plane that I explained in the reply to your previous question then the concept of |a+ib| can be seen geometrically. The proofs of limit laws and derivative rules appear to tacitly assume that the limit exists in the first place. It only takes a minute to sign up. neighbouring pixels : next smaller and bigger perimeter. $$i^i = e^{ii(\frac{\pi}{2}+2\pi n)} = e^{\frac{-\pi}{2} + 2\pi n} ~~~~~~~~~~ n\in \Bbb{Z}$$$i^i=e^{(\frac{1}{2}i\pi)*i} = e ^ {-\frac{1}{2}\pi}$, The reason why it doesn't seem right is because of the following. The principal value of would be --the case where n=0. Q What do you understand by Actual Quality Level value AQL Q Which are the top ten brands of the world as ranked by interbrand in 2002? How can you prove that a value raised to$\frac{1}{n}$is the n'th root of$x$? What is the term for diagonal bars which are making rectangular frame more rigid? As noted in particular by L.F., Argon and ncmathsadist, the answer depends on the branch of the complex logarithm you choose to work with. ( ̂ × ̂) + ̂. Yes, as L.F. said, log i can produce an infinite number of values, and is only a function upon selecting a branch$i(\frac{\pi}{2} + 2\pi n). How do they determine dynamic pressure has hit a max? However, |e^1000000i| is still just 1. a) A sentinel is a value that creates a bridge between a data set and unrelated input. It removes all 4s, 5s and 6s from values 3. Thus to look at i i one could consider i i = (e i π /2) i and that's the same as e (i π /2)i = e (i 2)(π /2) = e-π /2. But $\log i = i\left(\frac{\pi}{2}+2\pi n\right)$, so we have Can 1 kilogram of radioactive material with half life of 5 years just decay in the next minute? What are the key ideas behind a good bassline? If you make a magic weapon your pact weapon, can you still summon other weapons?

Step-by-step explanation: To find: The correct option to this question is = Because: i raised to an odd power is = i. i, i.e., iota is an imaginary number which is mathematically equals to √(-1) It has been proven that the powers of iota give the value plus or minus i. This page will show you how to do this. log (i) has a value of approximately 0.68i, which would give: x = i^i log (x) = i log (i) = i i*0.68 = -0.68 x = 10^ (-0.68) = approximately 0.2079. The square of an imaginary number bi is −b 2.For example, 5i is an imaginary number, and its square is −25.By definition, zero is considered to be both real and imaginary. So iⁱ = (e^(i(4k+1)π/2))ⁱ = e^(i²(4k+1)π/2) = e^(-(4k+1)π/2) for all Integers k. Some values of iⁱ (for k = -2 to 2) are: e^(7π/2) ≈ 59609.7 e^(3π/2) ≈ 111.318 e^(-π/2) ≈ 0.20788 e^(-5π/2) ≈ 0.000388203 e^(-9π/2) ≈ 0.000000724947 So there isn't one specific value of iⁱ, but yes, they are all Real values. It is not well-defined. I mean, we can take $5\pi/2$ and get a different answer? Increment i (i becomes 1) Assign the value of step 1 to i (i becomes 0) Not that the increment is being discarded. What is imaginary infinity, $i\lim\limits_{x \to \infty} x = i\infty$? However, what happens when $i^i$ is performed? It removes the element at position 5 from values 4. The imaginary unit number is used to express the complex numbers, where i is defined as imaginary or unit imaginary. Autodetect radians/degrees. (However, while the square roots of a number always have the same magnitude even if they differ in sign, the values of have different magnitudes). This would be the principal one, and if the problem asks for one, this is it. I have always seen everywhere $\arg (re^{i\theta})=\theta +2k\pi$ (when $r>0$ and $\theta\in\mathbb{R}$). @Argon I know that, but it is still true, the argument of $i$ is $\frac{\pi}{2}$. The same thing must be done in complex analysis with the log function. $$z^x := e^{x\log z }$$ -8 B. For example, $$i^i=(\cos(\pi/2)+i\sin(\pi/2))^i=e^{i(i\pi/2)}=e^{-\pi/2}$$, for any complex number $z\in \mathbb C$ it can be written as $z=x+iy$ or in the polar form $z=re^{i\theta}$ where $r=\sqrt{x^2+y^2}$ and $\theta=\arctan(\frac{y}{x})$, so in particular $i=0+i1$ which implies that $r=1$ and $\theta=\frac{\pi}{2}$ Thus, $$i=e^{\frac{\pi i}{2}}$$ which implies that $$i^i=(e^{\frac{\pi i}{2}})^i=e^{\frac{-\pi }{2}}.$$, site design / logo © 2021 Stack Exchange Inc; user contributions licensed under cc by-sa. You seem to say that $\arg i=\pi/2+2\pi ik$. How to incorporate scientific development into fantasy/sci-fi? Can this equation be solved with whole numbers? Under a different branch you'll get a different result. I understand that when you raise any number $x$ to a power, you multiply $x$ by itself the number of times indicated in the power. Important! Well, in the complex numbers you consider an exponential of a base other than $e$, such as $z^x$, to be: So we have: Use the following calculator to find the current value of an I bond. Well i is equal to the square root of -1 so i is a real number and it approx. e. the sentinel value. An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i 2 = −1. e^{-\pi/2}$is the principal value with$n=0$. So what's the right answer? If i is an imaginary number. Answer: Step-by-step explanation: Powers of The Imaginary Unit. The value of 'i' is just 'i'. i^i=e^(-pi/2) (multipling the exponent by i raises to the power of i .and i*i=-1. in first step (i++) value is incremented by one but original value 10is used. 2. Hi, Since sine and cosine are periodic with period 2 π, for any integer n . Hi again Wayne If you use the complex plane that I explained in the reply to your previous question then the concept of |a+ib| can be seen geometrically. The proofs of limit laws and derivative rules appear to tacitly assume that the limit exists in the first place. It only takes a minute to sign up. neighbouring pixels : next smaller and bigger perimeter. $$i^i = e^{ii(\frac{\pi}{2}+2\pi n)} = e^{\frac{-\pi}{2} + 2\pi n} ~~~~~~~~~~ n\in \Bbb{Z}$$$i^i=e^{(\frac{1}{2}i\pi)*i} = e ^ {-\frac{1}{2}\pi}$, The reason why it doesn't seem right is because of the following. The principal value of would be --the case where n=0. Q What do you understand by Actual Quality Level value AQL Q Which are the top ten brands of the world as ranked by interbrand in 2002? How can you prove that a value raised to$\frac{1}{n}$is the n'th root of$x$? What is the term for diagonal bars which are making rectangular frame more rigid? As noted in particular by L.F., Argon and ncmathsadist, the answer depends on the branch of the complex logarithm you choose to work with. ( ̂ × ̂) + ̂. Yes, as L.F. said, log i can produce an infinite number of values, and is only a function upon selecting a branch$i(\frac{\pi}{2} + 2\pi n). How do they determine dynamic pressure has hit a max? However, |e^1000000i| is still just 1. a) A sentinel is a value that creates a bridge between a data set and unrelated input. It removes all 4s, 5s and 6s from values 3. Thus to look at i i one could consider i i = (e i π /2) i and that's the same as e (i π /2)i = e (i 2)(π /2) = e-π /2. But $\log i = i\left(\frac{\pi}{2}+2\pi n\right)$, so we have Can 1 kilogram of radioactive material with half life of 5 years just decay in the next minute?

It might be strange at first , but yes it is a real number under the principal branch. (i) (1 - i)x + (1 + i)y = 1 - 3i asked Aug 13 in Complex Numbers by Aryan01 ( 50.1k points) The value of is i. Step-by-step explanation: To find: The correct option to this question is = Because: i raised to an odd power is = i. i, i.e., iota is an imaginary number which is mathematically equals to √(-1) It has been proven that the powers of iota give the value plus or minus i. This page will show you how to do this. log (i) has a value of approximately 0.68i, which would give: x = i^i log (x) = i log (i) = i i*0.68 = -0.68 x = 10^ (-0.68) = approximately 0.2079. The square of an imaginary number bi is −b 2.For example, 5i is an imaginary number, and its square is −25.By definition, zero is considered to be both real and imaginary. So iⁱ = (e^(i(4k+1)π/2))ⁱ = e^(i²(4k+1)π/2) = e^(-(4k+1)π/2) for all Integers k. Some values of iⁱ (for k = -2 to 2) are: e^(7π/2) ≈ 59609.7 e^(3π/2) ≈ 111.318 e^(-π/2) ≈ 0.20788 e^(-5π/2) ≈ 0.000388203 e^(-9π/2) ≈ 0.000000724947 So there isn't one specific value of iⁱ, but yes, they are all Real values. It is not well-defined. I mean, we can take $5\pi/2$ and get a different answer? Increment i (i becomes 1) Assign the value of step 1 to i (i becomes 0) Not that the increment is being discarded. What is imaginary infinity, $i\lim\limits_{x \to \infty} x = i\infty$? However, what happens when $i^i$ is performed? It removes the element at position 5 from values 4. The imaginary unit number is used to express the complex numbers, where i is defined as imaginary or unit imaginary. Autodetect radians/degrees. (However, while the square roots of a number always have the same magnitude even if they differ in sign, the values of have different magnitudes). This would be the principal one, and if the problem asks for one, this is it. I have always seen everywhere $\arg (re^{i\theta})=\theta +2k\pi$ (when $r>0$ and $\theta\in\mathbb{R}$). @Argon I know that, but it is still true, the argument of $i$ is $\frac{\pi}{2}$. The same thing must be done in complex analysis with the log function. $$z^x := e^{x\log z }$$ -8 B. For example, $$i^i=(\cos(\pi/2)+i\sin(\pi/2))^i=e^{i(i\pi/2)}=e^{-\pi/2}$$, for any complex number $z\in \mathbb C$ it can be written as $z=x+iy$ or in the polar form $z=re^{i\theta}$ where $r=\sqrt{x^2+y^2}$ and $\theta=\arctan(\frac{y}{x})$, so in particular $i=0+i1$ which implies that $r=1$ and $\theta=\frac{\pi}{2}$ Thus, $$i=e^{\frac{\pi i}{2}}$$ which implies that $$i^i=(e^{\frac{\pi i}{2}})^i=e^{\frac{-\pi }{2}}.$$, site design / logo © 2021 Stack Exchange Inc; user contributions licensed under cc by-sa. You seem to say that $\arg i=\pi/2+2\pi ik$. How to incorporate scientific development into fantasy/sci-fi? Can this equation be solved with whole numbers? Under a different branch you'll get a different result. I understand that when you raise any number $x$ to a power, you multiply $x$ by itself the number of times indicated in the power. Important! Well, in the complex numbers you consider an exponential of a base other than $e$, such as $z^x$, to be: So we have: Use the following calculator to find the current value of an I bond. Well i is equal to the square root of -1 so i is a real number and it approx. e. the sentinel value. An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i 2 = −1. e^{-\pi/2}$is the principal value with$n=0$. So what's the right answer? If i is an imaginary number. Answer: Step-by-step explanation: Powers of The Imaginary Unit. The value of 'i' is just 'i'. i^i=e^(-pi/2) (multipling the exponent by i raises to the power of i .and i*i=-1. in first step (i++) value is incremented by one but original value 10is used. 2. Hi, Since sine and cosine are periodic with period 2 π, for any integer n . Hi again Wayne If you use the complex plane that I explained in the reply to your previous question then the concept of |a+ib| can be seen geometrically. The proofs of limit laws and derivative rules appear to tacitly assume that the limit exists in the first place. It only takes a minute to sign up. neighbouring pixels : next smaller and bigger perimeter. $$i^i = e^{ii(\frac{\pi}{2}+2\pi n)} = e^{\frac{-\pi}{2} + 2\pi n} ~~~~~~~~~~ n\in \Bbb{Z}$$$i^i=e^{(\frac{1}{2}i\pi)*i} = e ^ {-\frac{1}{2}\pi}$, The reason why it doesn't seem right is because of the following. The principal value of would be --the case where n=0. Q What do you understand by Actual Quality Level value AQL Q Which are the top ten brands of the world as ranked by interbrand in 2002? How can you prove that a value raised to$\frac{1}{n}$is the n'th root of$x$? What is the term for diagonal bars which are making rectangular frame more rigid? As noted in particular by L.F., Argon and ncmathsadist, the answer depends on the branch of the complex logarithm you choose to work with. ( ̂ × ̂) + ̂. Yes, as L.F. said, log i can produce an infinite number of values, and is only a function upon selecting a branch$i(\frac{\pi}{2} + 2\pi n). How do they determine dynamic pressure has hit a max? However, |e^1000000i| is still just 1. a) A sentinel is a value that creates a bridge between a data set and unrelated input. It removes all 4s, 5s and 6s from values 3. Thus to look at i i one could consider i i = (e i π /2) i and that's the same as e (i π /2)i = e (i 2)(π /2) = e-π /2. But $\log i = i\left(\frac{\pi}{2}+2\pi n\right)$, so we have Can 1 kilogram of radioactive material with half life of 5 years just decay in the next minute? What are the key ideas behind a good bassline? If you make a magic weapon your pact weapon, can you still summon other weapons? Find the real values of x and y for which the following equations are satisfied. The principal value of would be --the case where n=0. Power by imaginary numbers do not change the size of the result. The value of $i^i$ - is my method contradictory?

Why is it that (negative number) ^ (irrational number) is nonreal? Imaginary Numbers are not "Imaginary". An updated version is available every six months. How to learn Latin without resources in mother language. Therefore for$z=i$we get that$\ln i = \frac{i\pi}{2}$since$\arg i = \frac{\pi}{2}$. Autodetect radians/degrees. so we get.. j=10+(11) =21 Therefore, the values of are for any integer n. Note that there is more than one value for , just as 2 and -2 are both square roots of 4. Are you familiar with$e^{ix}=\cos x+i\sin x$? e i (2nπ +π /2) = cos(π /2 + 2n π) + isin(π /2 + 2n π) = cos(π /2) + isin(π /2) = i. One must be careful about complex powers; this is a branch-of-the-log consideration. Autodetect radians/degrees. It only takes a minute to sign up. taking the log of$a^b$(Project Euler problem 29). What is the meaning of: i = i++ + i;? 3.14 3E14 3,14 314 What is the value of the following literal?
