If anyone wants me to add one to the code and the output, I will gladly do so. Would be nice to have a very comprehensive list so user could check their u-sub, partial fractions, and intg by parts. I think the washer and shell method is left out way to often as well.
 
All code and output is free to use. I will never post anything that I won't allow reproduction of. Thus feel free to copy and edit code as you prefer. Again, we are all here to help one another! If you need anything in particular, feel free to post up a question and I will help to the best of my ability along with others.
 
Hello DrWahoo,

Please keep in mind MHB rule #1 states:
No bumping. Bumping a thread is posting a reply to that thread solely to raise its profile and return it to the top of the active threads list. This is forbidden at MHB. If you want to draw attention to an unanswered thread, then post something of value such as further progress. It is also forbidden to bump one thread by drawing attention to it in a different thread.

We discourage such posting behavior because such a post adds no value or content to a thread.
