Use a Grapher to Conjecture Whether the Equation Is Likely $\sin ^{2} x \cos ^{4} x=\cos ^{2} x+\cos ^{4} x-\cos ^{6} x$

Essay

Use a grapher to conjecture whether the equation is likely to be an identity. If it is not, give a counter example.
$\sin ^{2} x \cos ^{4} x=\cos ^{2} x+\cos ^{4} x-\cos ^{6} x$
