SUMMARY
The forum discussion centers on solving the separable differential equation dy/dx = [cos²(x)][cos²(y)]. The correct solution is y = (2n + 1)π/2, with clarification that the denominator is 2, not 4. Participants emphasize the need for accurate integration techniques and suggest using the identity cos²(x) = 1/2(1 + cos(2x)) to simplify the equation. The conversation highlights the importance of understanding the nature of solutions to differential equations, noting that there are infinitely many solutions beyond the particular ones discussed.
