About Course

 

From the book: "...intrinsic interest of the subject itself is enough motivation, but for most it is the likelihood of important applications to other fields that makes the understanding worthwhile. Many of the principles, or laws, underlying the behavior of the natural world are statements or relations involving rates at which things happen. When expressed in mathematical terms, the relations are equations and the rates are derivatives. Equations containing derivatives are differential equations ."

Direction Fields
Here is an link to an applet for plotting direction fields. Feel free to use it for your homework, these field take a lot of time to draw by hand. If you use the apple, print the applet drawing and the code you entered for it. In any case, make sure you know how to draw a direction field by hand: Direction Field Applet. Here is a link to how to draw direction fields and integral curves on a mac: Direction Fields on a Mac.

Integrating Factor
Here is handout I wrote explaining how to solve a linear differential equation of first order.
