It looks like you are asking for help in proving the following trig identity:Originally Posted byawesometrackgirl

cos(x)[sec^3(x)+cot(x)]=tan^2(x)/(1-cos^2(x)) + sin(x)/(sec^2(x)-1)

which is how we would normaly write this is plain ASCII.

It is easier to see what this is if we rewrite it in TeX:
