Problems listed here are unequivocally worth doing for practice. Those omitted from this list are omitted for a number of possible reasons - some are simple warm-ups that are unlikely to appear on a midterm or exam, some include at least one part that requires a computer or graphing calculator, some are of a slightly more theoretical nature than I don't expect you to be able to do on a midterm of exam and others may have just escaped my search by accident.
| Section | Problem numbers | Description |
|---|---|---|
| 1.1-1.2 | Most of these problems are introductory and would be good if you are confused about some of the basics. | |
| 1.3 | 1-6 | Classify by order, linearity |
| 7-14 | Verify that a given function is a solution to particular ODE. | |
| 19-20 | Find the value of $r$ so that $t^r$ solves the given ODE. | |
| 2.1 | 13-20 | Problems which can be solved using an integrating factor. Try using Method of Undetermined Coefficients as well for practice. |
| 30 | Choosing ICs to ensure boundedness of solutions | |
| 34-37 | Construct equations whose solutions have the prescribed asymptotic behaviour. | |
| 2.2 | 1-8 | Separable equations |
| 2.3 | 1-4 | Salt water inflow/outflow modeling problems |
| 17 | Stephan-Boltzmann heat loss. | |
| 18 | First order forcing (temperature). | |

| 17-18 | ||
| 21-24 | ||
| 28 | ||
| 3.2 | 1-6 | |

| 3.4 | 1-14 | |
| 23-30 | Reduction of order - omit this year (2014) | |
| 3.5 | 1-20 | |
| 30 | ||
| 3.7 | 1-4, 16 | Converting from sum of sin and cos to a single cos expression. |
| 6, 7, 11 | Mass-spring problems. | |
| 13, 14, 17, 20, 24, 26 | Mass-spring problems - parameter exploration. | |
| 15 | Superposition of IC solutions. | |
| 27 | An oscillating floating object. | |
| 3.8 | 1-4 | Sum of trig functions with different period (beats). |
| 5-8 | Set up (5,6) and solve (7,8) an IVP given a description of the physical system (forced mass-spring). | |
| 9, 10, 11, 17, 18 | Forced mass-spring problems. | |
| 7.9 | 22, 23 from 7.1 | Two-tank mixing problem; for both of these, also solve the system of equations from part (a). |
