How do you solve a Differential equation using integrating factors?
Check the equation is in the form dy/dx + P(x) y=Q(x) (show example) Find the int factor: I(x)=eintegralP(x) dxMultiply all terms by the integrating factorMake sure you show this step clearly: d/dx(I(x)y) =I(x)Q(x) Integrate both sides and add c.
