Question

prove the following cos^2 theta tan^2 theta = sin^2 theta​

Answer 1

Answer:

tan^2theta = sin^2theta/cos^2theta

cos^2theta×sin^2theta /cos^2theta

cos vaale cancel ho jayenge

=sin^2theta is the answer

Answer 2

Step-by-step explanation:

Given (cos 2 θ−sin 2 θ)=tan 2 ϕ

To prove:

cosϕ= 2 cosθ1

(cos 2 θ−sin 2 θ)=tan 2 ϕ

add 1 on both sides
