$4 \sin (4 y) = 16 \sin (y \cos^{3} (y - 16 \sin^{3} (y \cos (y))))$

Step 1

Subtract $16 \sin (y \cos^{3} (y - 16 \sin^{3} (y \cos (y))))$ from both sides of the equation.

$4 \sin (4 y) - 16 \sin (y \cos^{3} (y - 16 \sin^{3} (y \cos (y)))) = 0$

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.
