Expert Solution
Step 1

NOTE: Refresh your page if you can't see any equations.

.

y'=\cos ^2\left(x\right)\cos ^2\left(2y\right)

\frac{dy}{dx}=\cos ^2\left(x\right)\cos ^2\left(2y\right)

\frac{1}{\cos ^2\left(2y\right)}dy=\cos ^2\left(x\right)dx

\sec ^2\left(2y\right)dy=\cos ^2\left(x\right)dx
