Homework Statement
Find the function M such that M(x, y)dx+(x^2-y^2)dy=0 is exact.
Homework Equations
This is an exact equation.
The Attempt at a Solution
Here's my work:
integral of (x^2-y^2)dy=yx^2-y^3/3+h(x)=C
2xy+h'(x)=M(x, y)
But the answer in the book is M(x, y)=2xy+f(x). How do I get to the answer from there?
