Lecture Notes
-
1. Introduction
-
2. First Order Linear Differential Equations and Bernoulli's Equation
-
3. Separable Differential Equations and some differences between
linear and non-linear equations
- Note that various techniques of integration are useful for
solving separable equations. The Web has many useful resources to
aid in learning and reviewing some of those techniques. For
example, do a search for "integration by parts" or "partial
fractions".
