I've been having some real trouble solving this differential equation, mainly because I can't figure out what method to use. The question is as follows:
Consider the differential equation:
a) Show that the given equation is not exact.
b) Find constants a and b for which is an integrating factor for the given equation.
c) Use part b) to solve the given equation.
I think it's easy to show that the ODE is not exact but I'm not sure how to do the rest...
Thanks a lot,
