Learn how to solve differential equations problems step by step online. Solve the differential equation dy/dx=cos(y)^2cos(2x). Group the terms of the differential equation. Move the terms of the y variable to the left side, and the terms of the x variable to the right side of the equality. Simplify the expression \frac{1}{\cos\left(y\right)^2}dy. Integrate both sides of the differential equation, the left side with respect to y, and the right side with respect to x. Solve the integral \int\sec\left(y\right)^2dy and replace the result in the differential equation.

Final answer to the problem

$y=\arctan\left(\frac{\sin\left(2x\right)+C_1}{2}\right)$
