Thread: Verifying trig identities

Hello,

I'm having difficulties verifying this problem, can some please help me out?

Problem: (tan-cot) / (tan^2) - (cot^2) = sin cos
if I'm right the problem should look like this...

((sin/cos)-(cos/sin)) / ((sin^2/cos^2)-(cos^2/sin^2))

what are the algebraic steps to verify this problem?


Thanks!

Yep, so far so good. I would then cross multiply to give only one denominator:





Therefore we get:

.

To remove the quartic recall the difference of two squares and that

Thanks for the help! I was having difficulties with dividing fractions
