cos(1/2 x)=0

cos (\frac{1}{2} x) = 0

x = π + 4 πn, x = 3 π + 4 πn

Solution steps

cos (\frac{1}{2} x) = 0

General solutions for

cos (\frac{1}{2} x) = 0

\frac{1}{2} x = \frac{π}{2} + 2 πn, \frac{1}{2} x = \frac{3 π}{2} + 2 πn

Solve

\frac{1}{2} x = \frac{π}{2} + 2 πn : x = π + 4 πn

Solve

\frac{1}{2} x = \frac{3 π}{2} + 2 πn : x = 3 π + 4 πn

x = π + 4 πn, x = 3 π + 4 πn

\frac{4 cos ( θ ) - 1}{tan ( θ )} = 2 sin (θ)

- 2 sin^{2} (x) - cos (x) = - 1, 0^{\circ} \leq x < 36 0^{\circ}

cos^{2} (θ) - 3 cos (θ) + 2 = sin^{2} (θ)

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

2 + 2 sin (θ) = - 4 sin (θ)
