Question

Cos2theta cos theta son theta / cos theta sin theta sin 2 theta

Answer 1

Step-by-step explanation:

hope you will understand

Answer 2

Step-by-step explanation:

cos2A*cosA*sinA/cosA*sinA*sin2A

cosA and sinA will get cancelled.

cos2A/sin2A

Substituting formula,

What is the ans. you want according to that put formula.

cos2A=cos^2A-sin^2A

=1-2sin^2A

=2cos^2A-1

sin2A=2sinA*cosA
