How do you manually calculate i to the power of i?

i (taken to be sqrt(-1) for this question) requires that you know a bit about writing complex numbers. i = e^(i*pi/2) so i^i = (e^(i*pi/2))^i which equals e^(i*i*pi/2) since i*i = -1 we get e^(-pi/2) so i^i = e^(-pi/2) which is roughly .207879576


How can you make rational of i power i?

It is NOT rational, but it IS real.Start with Euler's formula: e^ix = cos(x) + i*sin(x) for all x.When x = pi/2,e^(i*pi/2) = cos(pi/2) + i*sin(pi/2) = 0 + i*1 = ior i = e^(i*pi/2)Raising both sides to the power i givesi^i = e^[i*(i*pi/2)] = e^[i*i*pi/2]and since i*i = -1,i^i = e^(-pi/2) = 0.20788, approx.


What is e to the power if i pi?

-1. It is a version of Euler's formula.


Is a power a whole number?

Not necessarily. i times pi is not a whole number, and yet e to the power of i times pi is equal to -1.


What Is The Definition Of Exponential Function In Math?

y = exWhatever your value of x is, you raise e to that power. e is a "transcendental" number like pi, and it equals 2.718281828459045 ...


What is the smallest number such that tan e to power x equals 1?

When x = 3.806663, tan(e^x) = 1.


Which distribution emits a probability density function f x equals 1 over square root of 2 pi times e to the power of minus x squared divided by 2?

That's a Gaussian distribution.


How do you answer E squared times 2 to the 5th power times 3 divided by 6 to the 7th power times 3 minus 4 squared times pi equals 42?

The answer depends on what the question is!


Why is Euler's formula important?

Euler's formula is important because it relates famous constants, such as pi, zero, Euler's number 'e', and an imaginary number 'i' in one equation. The formula is (e raised to the i times pi) plus 1 equals 0.


What mathematical property does e have that pi does not?

Many properties. For example, 1 + 1/1! + 1/2! + 1/3! + 1/4! + ... = e. This is not true for pi.


What did Albert Einstein discover besides E equals mc2?

yes he invented pi


What is e to the power of you times pi?

'e' is an imaginary number, multiplied by anything gives an imaginary result
