$\cos (2 x - 4) = \sin (6 x)$

Step 1

Subtract $\sin (6 x)$ from both sides of the equation.

$\cos (2 x - 4) - \sin (6 x) = 0$

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.
