Answer 1

Answer:

nahi pata muje sorry ok bhai ya bhen

Answer 2

Step-by-step explanation:

cosec6θ=(cosec2θ)3.

cosec2θ=cot2θ+1−−−−(1)

(cosec2θ)3=(cot2θ+1)3

Since (x+y)3=x3+y3+3xy(x+y),we have

cosec6θ=(cot2θ)3+(1)3(cot2θ)(1)(cot2θ+1)

⇒cosec6θ=cot6θ+1+3.cot2.cosec2θ

⇒cosec6θ=cot6θ+3.cot2cosec2θ+1

∴ L.H.S=R.H.S
