Question

find general solution of sin theta + cos theta + 1 = 0​

Answer 1

Answer:

θ=nπ+{(−1)n−1}4π,n=0,±1,±2

Step-by-step explanation:

We have, sinθ+cosθ=1

Multiplying both sides by 21 , we get

21sinθ+21cosθ=21

⟹sinθcos4π+cosθsin4π=sin4π

⟹sin(θ+4π)=sin4π

General solution:

⟹θ+4π=nπ+(−1)n
