Question

(cosec theta-cot theta)2=1-cos theta/1+cos theta

Answer 1

LHS: (cosec theta - cot theta)2

( 1/sin theta - cos theta / sin theta )2

[(1-cos theta)/ sin theta] 2

[(1- cos theta)(1-cos theta)]/[(1-cos theta)(1+ cos theta)]

(1-cos) theta gets cancelled.

(1-cos theta)/(1+cos theta)

LHS = RHS (proved)
