Is there an easier way of computing an integrating factor for differential equations? I need help understanding how to calculate those. I know the reason for them but just not familiar with how to compute exponential power functions. Help please
Integrating factors -- how in the world does one calculate those?

0Do you have some set of particular differential equations in mind? There are lots of types of integrating factors, some more obscure than others. – 2011-07-03

1For a general first-order DE of the form $f(x,y) dx + g(x,y) dy = 0$, computing an integrating factor is exactly as hard as solving the DE. Only if there happens to be an integrating factor of a special form can you hope to do it directly. – 2011-07-03

0Back from recent holiday. Well, I wanted to know if there was some easier way of generating the integration factor without needing to use exponential. :) – 2011-07-06
