Question

Please answer me it's very much important for me don't answer for points Please who know answer this
(sin θ + tan θ)2

Answer 1

Answer:

(sin(θ)+cos+(θ))^2=sin(2θ)+1

Explanation:

(sin(θ)+cos(θ))^2=sin^2(θ)+2sin(θ)cos(θ)+cos^2(θ)

We know that sin^2(θ)+cos^2(θ)=1 so

(sin(θ)+cos(θ))^2=2sin(θ)cos(θ)+1

However, 2sin(θ)cos(θ)=sin(2θ) so we can say

(sin(θ)+cos(θ))^2=sin(2θ)+1
