The exam on Feb 16  will cover the following sections:

1.1 (yes, you will see some direction fields on the exam), 1.2) linear
equations with constant coefficients, initial value problems, 
1.3)linear and non-linear ODE's, 2.1) integrating factors for a linear
ODE, 2.2) separable equations 2.3) tanks etc, 2.5) Autonomous equations,
equilibrium points, stability and instability, applications,
linearization (not in book), bifurcation diagrams page 93 25-27, 2.9)
linear difference equations, fixed points, stability and instability.
3.1) homogeneous equations with constant coefficients 3.3) linear
dependence and independence.

There will be an extra credit problem (or two) on the exam. These
are usually difficult!  If it works out the way I want it to, the exam
itself will not be difficult.
