Solving Ri(t)+Ld$\frac{di(t)}{dt}=V_{m}sin(wt+\theta)

[aztect]

Can anyone help me with this?
$$Ri(t) + L\frac{di(t)} {dt}=V_{m}sin(wt+\theta)$$

Hint:
What is the integrating factor here?

 

[aztect]

$$\exp\int\frac{R}{L}dt$$?

 

[arildno]

Which can be written more simply as..:?(assuming R, L constants, that is)

 

[aztect]

$$\exp\int{x}dt$$
