Cos θ = √(3)/2 include all solutions,

Question

Solve the following equation. Be sure to include all solutions 

cos θ = √(3)/2 

Answer 1

cos θ = √(3)/2

cos θ = cos (30^o)

α = 30^o

General solution formula : θ = 360^on ± α, where n is an integer.

θ = 360^on ± 30^o

Solution : θ = 360^on ± 30^o where n = 0 , 1 , 2 .......
