Establish the following identity:
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.
(cross multiply flipped denominator?)
Step 3. FOIL the sinx/cosx
Step 4. Fid a common denominator to get:
I don't see how to simplify any further to get it to match the "Right Hand Side".
