Homework Assignments

Note that following homework list can change at anytime. I will be updating the dates as the semester progresses.

Homework will usually be due on Thursdays. Note that following homework list can change at anytime and dates will change as the semester progresses. When changes are made, they will occur weeks in advance. I may change the order of some of the later chapters.

Maple Help

Maple Basics.pdf

Maple_intro_Print.pdf At the very end is an example relavant for DEs.

There are additional Maple examples inserted into the sections where they are applicable.

Homework is only accepted at the beginning of class.
