Question

Please solve this problem please it's very very very very very very very very very very very very very very very very very very very very very very very very very very very very very urgentttttt!

Answer 1

cosθ(1+sinθ)+cosθ(1−sinθ)/(1−sinθ)(1+sinθ)=4

cosθ+sinθcosθ+cosθ−sinθcosθ/1−sin^2θ=4

2cosθ/cos^2θ=4

2/cosθ=4

2=4cosθ

12=cosθ

θ=cos−1(12)

θ=±60+360∘n

Answer 2

HOPE THIS WILL HELP U ^_^
