# Thread: integrating factor?

1. ## integrating factor?

i need to find the general solution of the differential equation.

e^x(y'+y)=1/x

i need to use the intgrating factor exp(integralp(x)dx). but when i use the equation i am unable to finish the question. can anyboday help?

2. ## Re: integrating factor?

What was the integrating factor you used? Remember it needs to be in the form $\frac{dy}{dx}+P(x)y=f(x)$.

3. ## Re: integrating factor?

i divide by e^x. so the equation being dy/dx+(1/e^x)y=1/xe^x.
P(x)will be 1/e^x.
