0=2+4sin(x)

0 = 2 + 4 sin (x)

x = \frac{7 π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

Degrees

x = 21 0^{\circ} + 36 0^{\circ} n, x = 33 0^{\circ} + 36 0^{\circ} n

Solution steps

0 = 2 + 4 sin (x)

Switch sides

2 + 4 sin (x) = 0

Move

2

to the right side

2 + 4 sin (x) = 0

Subtract

2

from both sides

2 + 4 sin (x) - 2 = 0 - 2

Simplify

4 sin (x) = - 2

4 sin (x) = - 2

Divide both sides by

4

4 sin (x) = - 2

Divide both sides by

4

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

Simplify

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

Simplify

\frac{4 sin ( x )}{4} : sin (x)

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

Divide the numbers:

\frac{4}{4} = 1

= sin (x)

Simplify

\frac{- 2}{4} : - \frac{1}{2}

\frac{- 2}{4}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{2}{4}

Cancel the common factor:

2

= - \frac{1}{2}

sin (x) = - \frac{1}{2}

sin (x) = - \frac{1}{2}

sin (x) = - \frac{1}{2}

General solutions for

sin (x) = - \frac{1}{2}

x = \frac{7 π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

x = \frac{7 π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

sin (x) = \frac{1}{5}

cos (x) + cos (x) tan (x) = 0

4 sin^{3} (x) - sin (x) = 0

sin (θ) = 0.49

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