verify that
(cos x +1)/(tan^2 x) = (cos x)/(sec x -1)

i'm having way too much trouble with these problems.

always start with the left hand side and manipulate to find the right hand side. Here's a start...

\(\displaystyle \frac{\cos x +1}{\tan^2 x}= \frac{\cos x }{\tan^2 x}+\frac{1}{\tan^2 x}= \dots\)

well i know we can manipulate the left side in a few ways but it requires creativity and i can't do it.

I'd say it takes practice more than creativity :)
