Question

Cotpheta•sin2pheta=

1+cos2pheta
1+cospheta
1+sin2pheta ​

Answer 1

Explanation:

Did you mean.

`= \cot( \theta) . \sin(2 \theta)`

`= ( \cos( \theta) )/( \sin( \theta) ) .(2 \sin( \theta) \cos( \theta) )`

`= \frac{2 \sin( \theta) \cos {}^(2) ( \theta) }{ \sin( \theta) }`

`= 2 \cos {}^(2) ( \theta)`

`= 2.(1 - \sin {}^(2) ( \theta) )`

`= 2 - 2 \sin {}^(2) ( \theta)`

No option Solution.
