agar khud se solve kar lo

. itna to hm umid kar sakte hai.....

Answer 2

Given:- sin θ + sin² θ = 1

To find:- cos² θ + cos⁴θ

Solution:-

sin θ + sin² θ = 1

[tex]\implies[tex] sin θ + 1-cos²θ = 1

[tex]\implies[tex] sinθ - cos²θ = 0

[tex]\implies[tex] sinθ = cos²θ

[tex]\implies[tex]sin²θ = cos⁴θ

[tex]\implies[tex]1-cos²θ = cos⁴θ

[tex]\implies[tex]cos⁴θ + cos²θ = 1
