Homework Statement
dy/dx =[cos^2(x)][cos^2(y)]
Homework Equations
The solution to this problem is y = +/- [(2n + 1)*pi]/4
How? Do i just plug C back into the equation? That seems a little messy
The Attempt at a Solution
dy/cos^2(y) = cos^2(x) dx
After integrating: (1/2)tan(2y) = (1/2)(x + cos(x) + sin(x) + C)
C = 2tan(2y) - 2x -sin(2x) for cos(2y) not = 0
