Question

This is not a question.
Surprising result - I came across this in a text chapter about complex numbers.
We wish to find i^i
i in polar form is cos pi/2 + i sin pi/2 =
e ^(i pi/2)
So i^i = (e^(i pi/2)^i = e^(-pi/2) = approx 0.207.
a real value!

Answer 1

* text book chapter

Answer 2

oh I have no idea what that means (at least not at this moment since I still have a lot more to learn) :)

Answer 3

Complex numbers is a fascinating subject. I am not sure if this makes sense really. I think its a matter for someone expert in mathematical analysis.

Answer 5

GCE A levels?

Answer 6

try googling them

Answer 20

Ha!!
I just wanted that xD

Answer 21

ok

Answer 22

nice result
