Wolfram Alpha is a thing, you know.

Guess integrals/differentials aren't taught in schools anymore?

As well as common sense.

For both those equations to intersect both equations are equal to each other

so

cos 2x = cos^2 x-1

were not doing your hw dipshit

Exactly

Why lie to him? Though if he can't even grab a calculator to check it...
