Okay, for this one I need to somehow get sinx to equal to the square root of 1 over 1+cot(squared)x.

The identity looks like this:

-sinx = √1

-------1+cot^2x

So could someone show me in detail how I would solve this identity?

Learn LaTeX. You can download the Latex.pdf tutorial and look at the basic commands.

How'd you solve it? I need to show my work, plus knowing how it was done will help me in the future.

You should end off with OR

and remember to reject the negative answer
