Find the domain of the function y = cos ^ 2x / -2x.

Find the domain of the function y = cos ^ 2 x / (- 2 * x).

The domain of the function is when the denominator of the fraction is not equal to 0 and the trigonometric function cos x belongs to [- 1; one]. That is, we get:

{- 1 <= cos x <= 1;

– 2 * x is not equal to 0;

{- 1 <= cos x <= 1;

x is not 0.
