Supplementary Material

1. Review of some useful facts and formulas from algebra and calculus
 several formulas with illustrative examples that will be useful throughout the term:
 exponentials and natural logs, trig formulas, integration (elementary functions, substitutions,
integration by parts, partial fractions.

2. Examples: classifying linear homogeneous/nonhomogeneous, and nonlinear differential equations.

3. More examles of solving 1st order linear nnonhomogeneous DE

4. An example illustrating use of partial fractions and calculation of  intervals of existence for a separable equation

5. Application: example using Newton's law of cooling (continuation of example discussed during lecture on 2/23).

6. Application: mixing problem in solution with a  time-varying volume.

7. Lecture notes for material first order DE:
linear DE
separable DE
Applications: 1 2
(second link includes  material on pop dynamics and exact DE, which will not be on Exam I)

8. Example on population dynamics (as presented in class-along with calculation of interval of existence).

9.Writeup of damped spring mass problem from Lecture on Wednesday, April 15

10.Formula sheet for Exam II

11. Extra lectures notes material on Laplace Transforms (more examples, etc)
