4sin(2x)=0,-pi<= x<= pi

4 sin (2 x) = 0, - π \leq x \leq π

x = 0, x = \frac{π}{2}, x = π, x = - π, x = - \frac{π}{2}

Degrees

x = 0^{\circ}, x = 9 0^{\circ}, x = 18 0^{\circ}, x = - 18 0^{\circ}, x = - 9 0^{\circ}

Solution steps

4 sin (2 x) = 0, - π \leq x \leq π

Divide both sides by

4

4 sin (2 x) = 0

Divide both sides by

4

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

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

Solutions for the range

- π \leq x \leq π

x = 0, x = \frac{π}{2}, x = π, x = - π, x = - \frac{π}{2}

cos (x) = - 0.6987

sin (2 x) = \frac{( 2 m - 3 )}{3}

x, y = 5 arccos (2 x)

sin (3 x) = \frac{2}{2}, 0 \leq x \leq 2 π

\frac{cot ( x )}{cos ( x )} + \frac{1}{sin ( x )} = 1
