Originally Answered: What is the value of I^i? How many things can a person hold and use at one time? 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. Can this equation be solved with whole numbers? It is not well-defined. 2. 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. in first step (i++) value is incremented by one but original value 10is used. neighbouring pixels : next smaller and bigger perimeter.

Is it my fitness level or my single-speed bicycle? @Argon I know that, but it is still true, the argument of $i$ is $\frac{\pi}{2}$. 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. Autodetect radians/degrees. Why is it that (negative number) ^ (irrational number) is nonreal? The loop can best be categorized as a: a. I think I was on the wrong path to the right number, if I had considered the order doesn't matter you get 2x-2x^2 as the probability, integrate from [0,1] to … 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. When a microwave oven stops, why are unpopped kernels very hot and popped kernels not hot? The value of $i^i$ - is my method contradictory? Add your answer and earn points. $i^i=e^{(\frac{1}{2}i\pi)*i} = e ^ {-\frac{1}{2}\pi}$, The reason why it doesn't seem right is because of the following. 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). Hard to believe it's a real number but yeah, it is :P, @EricStucky I edited the question to make it better readable and added the minus sign.

How to incorporate scientific development into fantasy/sci-fi? Just type your power into the box, and click "Do it!" New questions in Mathematics. Well i is equal to the square root of -1 so i is a real number and it approx. -4 C.4 D. 8 acm9e7auap is waiting for your help. I think it should be mentioned that $e^{-\frac{\pi}{2}}$ is the. However, what happens when $i^i$ is performed? i times i is i squared which will give you negative 1. i^15 = -i Remember that i^2 = -1. I Values Table. 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. 11 is used. c) A sentinel is a value that terminates a program. BTW the answer ($e^{-\frac{1}{2}\pi}$) seems perfectly valid to me. tan/tg tangent of a value or expression. Can 1 kilogram of radioactive material with half life of 5 years just decay in the next minute? 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. CPA Chapter 1 Assessment Answers 100% Which of the following strings is a proper integer number (in the “C++” language sense)? $$i^i = e^{i\log i}$$ (|a+ib| is usually called the modulus of a+ib rather than its absolute value.) 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. What is the term for diagonal bars which are making rectangular frame more rigid? Autodetect radians/degrees. Well, in the complex numbers you consider an exponential of a base other than $e$, such as $z^x$, to be: If i is an imaginary number. (Photo Included). $$i^i = e^{ii(\frac{\pi}{2}+2\pi n)} = e^{\frac{-\pi}{2} + 2\pi n} ~~~~~~~~~~ n\in \Bbb{Z}$$ (6-5i)^(-3+32i) = 2929449.03994-9022199.58262i i^i = 0.2078795764 pow(1+i,3) = -2+2i Functions sqrt Square Root of a value or expression. rev 2021.1.8.38287, The best answers are voted up and rise to the top, Mathematics Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us, Missing a minus sign, but that's the right idea.

Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share … So we have: A function must by 1-1 to possess an inverse. What Constellation Is This? e^5, is bigger than e^1. That kind of looks like DeMoivre's Theorem, but what exactly happens? 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 principal value of would be --the case where n=0. A simple solution is to generate all permutations of given array.For every permutation, compute the value of Σarr[i]*i and finally return the maximum value. ( ̂ × ̂) + ̂. Ceramic resonator changes and maintains frequency when touched, Quantum harmonic oscillator, zero-point energy, and the quantum number n. Why continue counting/certifying electors after one candidate has secured a majority? Imaginary Numbers were once thought to be impossible, and so they were called "Imaginary" (to make fun of them).. 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. Is there any way to make a nonlethal railgun? (that is the principal angle) This matches your result. You seem to say that $\arg i=\pi/2+2\pi ik$. It only takes a minute to sign up. This means that when you add i twice, it now has the value of 7. It removes all 4s, 5s and 6s from values. A periodic function is not 1-1. Answer by Alan3354(67103) (Show Source): An efficient solution is based on the fact that the largest value should be scaled maximum and smallest value should be scaled minimum. @ncmathsadist: I see; you're saying it is essentially because $\sin$ is periodic? What is the smallest value of n such that an algorithm running at 100*n^2 operates faster than 2^n ? Log in to reply. (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). b) A sentinel is a value that is part of the data to be processed by the program. The value of i is the square root of -1, or √(-1). What's the link between logarithms and the zeroth power, if any? –i 0 –2i i Superscript 96 2 See answers elcharly64 elcharly64 The question is not clearly readable, but I'm assuming the expression which makes more sense, so you can have a clue. Is it normal to feel like I can't breathe while trying to ride at a challenging pace? 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. $$i^{i} = e^{-\pi/2 + 2k \pi}, \;\; k \in \mathbb{Z}$$, site design / logo © 2021 Stack Exchange Inc; user contributions licensed under cc by-sa. Hi, Since sine and cosine are periodic with period 2 π, for any integer n . Does there exist a universal formula of first-order logic that is satisfiable only by structures with infinite domains? To view the value data for all issued bonds, view the I Bond Value Table. So this exponent is pi*(-1)/2 ) e^(-pi/2)=0.2079. i++ first uses the value and then increments it. Thus, i^4 = (i^2)^2 = (-1)^2 = 1 Also, remember the power rule a^m * a^n = a^(m+n) Thus, you have i^15 = i^(4 + 4 + 4 + 3) = i^4 * i^4 * i^4 * i^3 = 1 * 1 * 1 * i^3 = i^3 = i^2 * i = -1 * i = -i =========== Also, I'd like to offer you a more general solution for i^n, with n being any positive integer. @Argon I understand what you mean, but may be I should've just written that $\theta=\frac{\pi}{2}$ without trying to explain it more. 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. i^i=e^(-pi/2) (multipling the exponent by i raises to the power of i .and i*i=-1. Important! Therefore for $z=i$ we get that $\ln i = \frac{i\pi}{2}$ since $\arg i = \frac{\pi}{2}$. If so, start by putting in $x=\pi/2$. Are you familiar with $e^{ix}=\cos x+i\sin x$? 1 decade ago The value of i is the square root of -1, or √ (-1). I would like to know what is the absolute value of i.
