Question

Cotpheta•sin2pheta=1+cos2pheta1+cospheta1+sin2pheta ​

Answer 1

Answer:

Step-by-step explanation:

Did you mean.

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

$= \frac{ \cos( \theta) }{ \sin( \theta) } .(2 \sin( \theta) \cos( \theta) )$

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

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

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

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

No option Solution.
