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

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

x = π + 2 πn

Solution steps

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

Solve by substitution

cos (x) = - 1

cos (x) = - 1 : x = π + 2 πn

Combine all the solutions

x = π + 2 πn

x, arctan (\frac{y}{x}) = 45

cos (H) = 0.3648447229

θ, cos (\frac{θ}{2} + 3 0^{\circ}) = sin (θ)

5 sin^{2} (θ) = 1 + 3 sin^{2} (θ)

5 sin (2 θ) - 8 sin (θ) = 0
