Question

Prove that : cosec2θ+cosec4θ=cotθ-cot4θ

Answer 1

Answer:

Consider L.H.S. = cosec4 θ – cosec2 θ

= (cosec2 θ)2 – (cosec2 θ)

= (1 + cot2 θ)2 – (cosec2 θ)

= 1 + cot4 θ + 2cot2 θ – (cosec2 θ)

= 1 + cot4 θ + cot2 θ – (cosec2 θ – cot2 θ)

= 1 + cot4 θ + cot2 θ – 1

= cot4 θ + cot2 θ

= R.H.S.

Hence, proved.
