$\sin^{2} (a) - \sin^{4} (a) = \cos^{2} (a) - \cos^{4} (a)$

Step 1

Graph each side of the equation. The solution is the x-value of the point of intersection.

$a \approx 0, - 0.1, 0.1, \frac{1}{5}, 0.3, \frac{2}{5}, - \frac{1}{2}$

Step 2

The result can be shown in multiple forms.

Exact Form:

$a \approx 0, - 0.1, 0.1, \frac{1}{5}, 0.3, \frac{2}{5}, - \frac{1}{2}$

Decimal Form:

$a \approx 0, - 0.1, 0.1, 0.2, 0.3, 0.4, - 0.5$
