You should have a rough idea about differential equations and partial derivatives before proceeding! Note: f y is our version of the constant of integration "C" because due to the partial derivative we had y as a fixed parameter that we know is really a variable. That "C" can be a different value to the "C" just before. 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:. But we can try to make it exact by multiplying each part of the equation by x m y n :.

Exact Equations and Integrating Factors
Exact equation , type of differential equation that can be solved directly without the use of any of the special techniques in the subject. A first-order differential equation of one variable is called exact, or an exact differential, if it is the result of a simple differentiation. The subscripts in this equation indicate which variable the partial derivative is taken with respect to.

This is a first order linear partial differential equation (PDE) for the function µ and to solve (a) For example, suppose we can find the integrating factor µ which is a function of x alone Therefore the general solution of (7) is given implicitly by.
