-6cos(θ)+4=4

- 6 cos (θ) + 4 = 4

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

Solution steps

- 6 cos (θ) + 4 = 4

Subtract

4

from both sides

- 6 cos (θ) + 4 - 4 = 4 - 4

Simplify

- 6 cos (θ) = 0

Divide both sides by

- 6

cos (θ) = 0

General solutions for

cos (θ) = 0

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

4 cos (x) = - sin^{2} (x) + 4

7 cos^{2} (θ) + 5 = 2 sin (θ) + 7

1 - cos (2 x) = 1 + cos (2 x)

5 cos^{2} (x) - 10 cos (x) + 5 = 0

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