-6sin(2x)=0

- 6 sin (2 x) = 0

x = πn, x = \frac{π}{2} + πn

Degrees

x = 0^{\circ} + 18 0^{\circ} n, x = 9 0^{\circ} + 18 0^{\circ} n

Solution steps

- 6 sin (2 x) = 0

Divide both sides by

- 6

- 6 sin (2 x) = 0

Divide both sides by

- 6

\frac{- 6 sin ( 2 x )}{- 6} = \frac{0}{- 6}

Simplify

sin (2 x) = 0

sin (2 x) = 0

2 x = 0 + 2 πn, 2 x = π + 2 πn

2 x = 0 + 2 πn, 2 x = π + 2 πn

Solve

2 x = 0 + 2 πn : x = πn

2 x = 0 + 2 πn

0 + 2 πn = 2 πn

2 x = 2 πn

Divide both sides by

2

2 x = 2 πn

Divide both sides by

2

\frac{2 x}{2} = \frac{2 πn}{2}

Simplify

x = πn

x = πn

Solve

2 x = π + 2 πn : x = \frac{π}{2} + πn

2 x = π + 2 πn

Divide both sides by

2

2 x = π + 2 πn

Divide both sides by

2

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

Simplify

x = \frac{π}{2} + πn

x = \frac{π}{2} + πn

x = πn, x = \frac{π}{2} + πn

sin (3 x) - 1 = 0

- sin (θ) = 0

sin (θ) = \frac{1}{6}

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

sin (\frac{x}{4}) = 0
