Section 9 Exercise Set
Solve the following ODE using either separable or linear methods. There will be
times where only one method can be used, and there will be times when both can be
used. If the problem is an IVP, make sure to solve for C.
(dr)/(dt)=(r)/(t)+2t+1
1. $\frac{dr}{dt} = \frac{r}{t} + 2t + 1$
