2sin(3x)+2=4

2 sin (3 x) + 2 = 4

x = \frac{π}{6} + \frac{2 πn}{3}

Degrees

x = 3 0^{\circ} + 12 0^{\circ} n

Solution steps

2 sin (3 x) + 2 = 4

Move

2

to the right side

2 sin (3 x) + 2 = 4

Subtract

2

from both sides

2 sin (3 x) + 2 - 2 = 4 - 2

Simplify

2 sin (3 x) = 2

2 sin (3 x) = 2

Divide both sides by

2

2 sin (3 x) = 2

Divide both sides by

2

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

Simplify

sin (3 x) = 1

sin (3 x) = 1

General solutions for

sin (3 x) = 1

3 x = \frac{π}{2} + 2 πn

3 x = \frac{π}{2} + 2 πn

Solve

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

3 x = \frac{π}{2} + 2 πn

Divide both sides by

3

3 x = \frac{π}{2} + 2 πn

Divide both sides by

3

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

Simplify

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

Simplify

\frac{3 x}{3} : x

\frac{3 x}{3}

Divide the numbers:

\frac{3}{3} = 1

= x

Simplify

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

\frac{\frac{π}{2}}{3} + \frac{2 πn}{3}

\frac{\frac{π}{2}}{3} = \frac{π}{6}

\frac{\frac{π}{2}}{3}

Apply the fraction rule:

\frac{\frac{b}{c}}{a} = \frac{b}{c \cdot a}

= \frac{π}{2 \cdot 3}

Multiply the numbers:

2 \cdot 3 = 6

= \frac{π}{6}

= \frac{π}{6} + \frac{2 πn}{3}

x = \frac{π}{6} + \frac{2 πn}{3}

x = \frac{π}{6} + \frac{2 πn}{3}

x = \frac{π}{6} + \frac{2 πn}{3}

x = \frac{π}{6} + \frac{2 πn}{3}

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

43 tan (x) + 4 = 0

- 2 cos (a) + 6 = cos (a) + 9

sin (θ) = 0.64

tan (θ) = \frac{6}{5}
