Question

prove that sin 2 theta divided by 1 - cos 2 theta equal to COT theta

Answer 1

sin 2theta decided by 1 - cos 2theta
= 2sin theta × cos theta/2sin square theta
= 2sin theta × cos theta/2×sin theta×sin theta
= cos theta/sin theta
= cot theta
(sin 2theta = 2sin theta × cos theta)
(1-cos 2 theta = 2sin square theta)
