Homework Help: Trigonometry

Posted by Timothy on Monday, February 25, 2008 at 7:36pm.

Hello all,

In our math class, we are practicing the trigonometric identities (i.e., sin^2(x)+cos^2(x)=1 or cot(x)=cos(x)/sin(x). Now, we are working on proofs that two sides of an equation are equal (for example, sin(x)*csc(x)=1; sin(x)csc(x)=sin(x)/sin(x)=1; 1=1). I am not having much trouble with these problems, but two are proving rather difficult for me. They are:

csc^2(x)/cot(x)=csc(x)sec(x)

and

cot^3(x)/csc(x)=cos(x)*csc^2(x)-1

Could I please get a kick in the right direction?

Thanks,

Timothy
