cos(x)=(4(-1/2)-1)/3

cos (x) = \frac{4 ( - \frac{1}{2} ) - 1}{3}

x = π + 2 πn

Solution steps

cos (x) = \frac{4 ( - \frac{1}{2} ) - 1}{3}

Simplify

\frac{4 ( - \frac{1}{2} ) - 1}{3} : - 1

General solutions for

cos (x) = - 1

x = π + 2 πn

1 = l sin (x), 2 = l cos (x)

y, t = 2 cot (6 0^{\circ} y + 3 0^{\circ})

sec (y) = - 2

- 1 + 2 sin^{2} (x) = 0

θ, y = - 2 + cos (3 θ)
