0=2cos(θ)

0 = 2 cos (θ)

θ = \frac{π}{2} + 2 πn, θ = \frac{3 π}{2} + 2 πn

Solution steps

0 = 2 cos (θ)

Switch sides

2 cos (θ) = 0

Divide both sides by

2

cos (θ) = 0

General solutions for

cos (θ) = 0

θ = \frac{π}{2} + 2 πn, θ = \frac{3 π}{2} + 2 πn

- 2 sin (x) - 2 cos (2 x) = 0

\frac{cos ( x )}{1 + sin ( x )} = 1 - \frac{sin ( x )}{cos ( x )}

y, 2 cos (5 x + y) = 0

2 cos^{2} (x) + 15 sin (x) - 15 = 0

cos (2 x) = sin (x), - 2 π \leq x \leq 2 π
