-2sin(4x)=0

- 2 sin (4 x) = 0

x = \frac{πn}{2}, x = \frac{π}{4} + \frac{πn}{2}

Degrees

x = 0^{\circ} + 9 0^{\circ} n, x = 4 5^{\circ} + 9 0^{\circ} n

Solution steps

- 2 sin (4 x) = 0

Divide both sides by

- 2

- 2 sin (4 x) = 0

Divide both sides by

- 2

\frac{- 2 sin ( 4 x )}{- 2} = \frac{0}{- 2}

Simplify

sin (4 x) = 0

sin (4 x) = 0

4 x = 0 + 2 πn, 4 x = π + 2 πn

4 x = 0 + 2 πn, 4 x = π + 2 πn

Solve

4 x = 0 + 2 πn : x = \frac{πn}{2}

4 x = 0 + 2 πn

0 + 2 πn = 2 πn

4 x = 2 πn

Divide both sides by

4

4 x = 2 πn

Divide both sides by

4

\frac{4 x}{4} = \frac{2 πn}{4}

Simplify

x = \frac{πn}{2}

x = \frac{πn}{2}

Solve

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

4 x = π + 2 πn

Divide both sides by

4

4 x = π + 2 πn

Divide both sides by

4

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

Simplify

x = \frac{π}{4} + \frac{πn}{2}

x = \frac{π}{4} + \frac{πn}{2}

x = \frac{πn}{2}, x = \frac{π}{4} + \frac{πn}{2}

2 sin (x) + 3 = 0, 0 \leq x \leq 2 π

cos (2 x) = 1 - sin (2 x), 0 \leq x \leq 2 π

0 = 1 + 2 sin (θ)

csc (x - \frac{π}{3}) = 2

sin (θ) = \frac{11}{6}
