cos(3x)*3=0

cos (3 x) \cdot 3 = 0

x = \frac{π}{6} + \frac{2 πn}{3}, x = \frac{π}{2} + \frac{2 πn}{3}

Solution steps

cos (3 x) \cdot 3 = 0

Divide both sides by

3

cos (3 x) = 0

General solutions for

cos (3 x) = 0

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

Solve

3 x = \frac{π}{2} + 2 πn : x = \frac{π}{6} + \frac{2 πn}{3}

Solve

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

x = \frac{π}{6} + \frac{2 πn}{3}, x = \frac{π}{2} + \frac{2 πn}{3}

16 sec^{2} (θ) - 25 = 0

2 csc^{2} (x) - 4 = 0

2 sin^{2} (θ) - 3 sin (θ) - 2 = 0, 0 \leq θ \leq 2 π

3 sin (2 θ) = 2 cos (2 θ), 0^{\circ} \leq 2 θ < 72 0^{\circ}

csc (x) + 2 = 0
