Question

2 sin cos - Coso 1 - sine + sin? o-cos is equal to (1) cose (3) tano (2) 1 (4) cote​

Answer 1

Answer:

sinθ+cosθ=

3

=(sinθ+cosθ)

2

=3

=sin

2

θ+cos

2

θ+2sinθcosθ=3

⇒2sinθcosθ=2

⇒sinθcosθ=1

⇒sinθcosθ=sin

2

θ+cos

2

θ

⇒1=

sinθcosθ

sin

2

θ+cos

2

θ

⇒tanθ+cotθ=1

Answer 2

Answer:
