Question

Verify the identity. Justify Each Step.

Answer 1

\[\frac{ \sec \Theta }{ \csc \Theta - \cot \Theta} - \frac{ \sec \Theta }{ \csc \Theta + \cot \Theta } =2 \csc \Theta \]

Answer 2

Answer 3

I would start by changing all sec, csc and cot on the left side into expressions with sin and cos.
secA = 1/cosA
cscA = 1/sinA
cotA = cosA/sinA
