Web5 sep. 2024 · Integrate the first equation with respect to x to get f(x, y) = 2x2y + x + C(y). Notice since y is treated as a constant, we write C(y). Now take the partial derivative with … WebIntegrating Factors. Some equations that are not exact may be multiplied by some factor, a function u (x, y), to make them exact. When this function u (x, y) exists it is called an integrating factor . It will make valid the following expression: ∂ (u·N (x, y)) ∂x = ∂ (u·M (x, y)) ∂y. There are some special cases:
