$9 \cos (x) = - 3 \sqrt{3} \sin (x)$

Step 1

Add $3 \sqrt{3} \sin (x)$ to both sides of the equation.

$9 \cos (x) + 3 \sqrt{3} \sin (x) = 0$

Step 2

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
