Question

show that. cosec 2 theta - cot 2 theta = tan theta

Answer 1

(Cosec 2 theta = 1/Sin 2 theta)
( Cot 2 theta = Sin 2 theta / cos 2 theta)

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

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

2 sin square theta / 2 sin theta × cos theta

sin theta / cos theta = tan theta

Answer 2

this is your answer
