-2sqrt(3)sin(x)+2cos(x)=0

Solution

- 23 sin (x) + 2 cos (x) = 0

Solution

x = \frac{π}{6} + πn

Degrees

x = 3 0^{\circ} + 18 0^{\circ} n

Solution steps

- 23 sin (x) + 2 cos (x) = 0

Rewrite using trig identities

- 23 sin (x) + 2 cos (x) = 0

Divide both sides by

cos (x), cos (x) \neq = 0

\frac{- 2 3 sin ( x ) + 2 cos ( x )}{cos ( x )} = \frac{0}{cos ( x )}

Simplify

- \frac{2 3 sin ( x )}{cos ( x )} + 2 = 0

Use the basic trigonometric identity:

\frac{sin ( x )}{cos ( x )} = tan (x)

- 23 tan (x) + 2 = 0

- 23 tan (x) + 2 = 0

Move

2

to the right side

- 23 tan (x) + 2 = 0

Subtract

2

from both sides

- 23 tan (x) + 2 - 2 = 0 - 2

Simplify

- 23 tan (x) = - 2

- 23 tan (x) = - 2

Divide both sides by

- 23

- 23 tan (x) = - 2

Divide both sides by

- 23

\frac{- 2 3 tan ( x )}{- 2 3} = \frac{- 2}{- 2 3}

Simplify

\frac{- 2 3 tan ( x )}{- 2 3} = \frac{- 2}{- 2 3}

Simplify

\frac{- 2 3 tan ( x )}{- 2 3} : tan (x)

\frac{- 2 3 tan ( x )}{- 2 3}

Apply the fraction rule:

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

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

Divide the numbers:

\frac{2}{2} = 1

= \frac{3 tan ( x )}{3}

Cancel the common factor:

3

= tan (x)

Simplify

\frac{- 2}{- 2 3} : \frac{3}{3}

\frac{- 2}{- 2 3}

Apply the fraction rule:

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

= \frac{2}{2 3}

Divide the numbers:

\frac{2}{2} = 1

= \frac{1}{3}

Rationalize

\frac{1}{3} : \frac{3}{3}

\frac{1}{3}

Multiply by the conjugate

\frac{3}{3}

= \frac{1 \cdot 3}{3 3}

1 \cdot 3 = 3

33 = 3

33

Apply radical rule:

a a = a

33 = 3

= 3

= \frac{3}{3}

= \frac{3}{3}

tan (x) = \frac{3}{3}

tan (x) = \frac{3}{3}

tan (x) = \frac{3}{3}
