Substitution for integration of e^(x*y) dx

  1. Apr 18, 2012 #1
    Really not sure... Does any one know an appropriate substitution?

    The whole problem is:

    Find the substitution that simplifies the differential equation

    x(dy/dx) + y = e^(x*y)

    What is
    [tex]\frac{d(xy)}{dx}[/tex]
    ?

    I know the first part. It is the integration of e^(x*y) that I am having problems with, as it requires a substitution...

    don't you think that afterwards you will have too many (x*y)s?

    one more sentence and the other party will have to solve it -_-

    I understand that- and if you had answered my question, it should have become obvious to you what substitution you need.
