Hey, I have been trying to figure out how to do these problems for quite some time, but I'm stuck. Help is very much appreciated.
2- ((sin^2(x)/tan^2(x))= sin^2x-1
I really cannot figure this out.
Also, how do you solve this problem for theta? (this is one where I'm supposed to find the reference angle):
and last thing, how do you find the cot(M+N)? Is it the same as the sum formula for cos but under 1?
Thank you so much!
Sin's ref <= 0 and cos's=180
so that means that u can = 0 degrees, 180 degrees or 360 degrees for sin, or 180 degrees for cos?
Hopefully that makes sense
at that point I get 2-cos^2(x), but I need it to be sin^2(x)-1
