Solution for x(1+y^2)dx-y(1+x^2)dy=0 equation:


Simplifying
x(1 + y2) * dx + -1y(1 + x2) * dy = 0

Reorder the terms for easier multiplication:
x * dx(1 + y2) + -1y(1 + x2) * dy = 0

Multiply x * dx
dx2(1 + y2) + -1y(1 + x2) * dy = 0
(1 * dx2 + y2 * dx2) + -1y(1 + x2) * dy = 0
(1dx2 + dx2y2) + -1y(1 + x2) * dy = 0
