### Re: Establishing an identity: tan(x)/(tan^2(x)-1)=1/(tan(x)-

Well, I attempted the problem using your suggestion and I was able to reduce it to this, but do not see any further simplification possibilities: http://img339.imageshack.us/img339/1599/identity.gif The denominator could be changed to -cos(2x), but I don't see that helping. The denominator could be ...

### Establishing an identity: tan(x)/(tan^2(x)-1)=1/(tan(x)-cot(

Establish the following identity: \frac{\tan(x)}{\tan^2(x)\, -\, 1}\, =\, \frac{1}{\tan(x)\, -\, \cot(x)} Please help, I'm not sure if I'm starting this correctly. My attempt was(using "Left Hand Side"): · Convert the tan and tan^2 to sin(x)/cos(x) and sin^2(x)/cos^2(x) respectively. \mbox{Step 1. }...
