Question

Math Analysis: Prove the given identity
cot 0 - tan 0/sin 0*cos 0=csc^2 0 - sec^2 0

Answer 1

cot 0 - tan 0/sin 0*cos 0 is a bit ambiguous... do you mean
\[\cot \theta-\frac{\tan \theta}{\sin \theta * \cos \theta}\]

Answer 2

yah but cot 0 and tan 0 share common denominators with each other :P

Answer 3

or this...
\cot \theta-\frac{\tan \theta}{\sin \theta}*cos theta
