Need help with complex numbers

8 posts in this topic

I have an exam coming up and I'm a little stuck on a complex number question. I've done the majority of it (or understood most of it) but there's one thing I'm stuck on:

i being the square root of -1

why is e^-i*pi/4 equal to e^i*7pi/4?

Haha that's alright :) I did my test and I think it went pretty well and there wasn't actually anything where you needed to know this particular thing anyway but thanks for asking :)
