cos(wpi)=0

cos (w π) = 0

w = \frac{1}{2} + 2 n, w = \frac{3}{2} + 2 n

Solution steps

cos (w π) = 0

General solutions for

cos (w π) = 0

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

Solve

w π = \frac{π}{2} + 2 πn : w = \frac{1}{2} + 2 n

Solve

w π = \frac{3 π}{2} + 2 πn : w = \frac{3}{2} + 2 n

w = \frac{1}{2} + 2 n, w = \frac{3}{2} + 2 n

2 tan (x) + sec^{2} (x) = 0, - 9 0^{\circ} < x < 9 0^{\circ}

tan (6 0^{\circ} - θ) = \frac{1}{3}

x, 1 - 2 cos (x) = 0

0 = 1 + sin (θ)

2 cos (2 x) - cos (x) - 1 = 0
