Some equations that are not exact may be multiplied by some factor, a So our general solution of I(x, y) = C becomes:

Now we evaluate the derivative with respect to y This time we will evaluate I(x, y) = в€«M(x, y)dx Since that was our first example, let's go further and make sure our solution is correct. But they both mean 'any constant', so let's call them C 1 and C 2 and then roll them into a new C below by saying C=C 1+C 2 Ooops! That 'C' can be a different value to the 'C' just before. 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.ДЄt the very start of this page we said that N(x, y) can be replaced by в€‚I в€‚y, so:ДЄnd the general solution (as mentioned before this example) is: Let's do the integration with x as an independent variable: They are the same! So our equation is exact. We evaluate the partial derivatives to check for exactness.
