# Math Help - imaginary roots?

1. ## imaginary roots?

what is the square root of "-i"? that is, not -1, but -i

if this is not the correct forum to ask this question, which forum or other internet site should I go to?

I would be very appreciative of any suggestion, help.

2. ## Re: question

Once you learn about polar complex representation, this will not be hard for you to compute.

The square root of -i is 1/sqrt(2)*[-1 + i]
