Best ResponseYou've already chosen the best response.0Period of \(b\sin^2x + a\cos^2x\) is same as \(c\sin^2x\). Use \(\sin^2\theta + \cos^2\theta = 1\).

Best ResponseYou've already chosen the best response.0\[4\sin^2x + 7\cos^2x = 4  11 \cos^2x\] Since \(\cos ^2x\)'s period \(\pi\), \(4  11 \cos^2x\) would \(\pi\) as well.
