Physics professor, Dr. Radi Jishi, received his PhD. in Physics from MIT. He carefully and methodically takes you through all the calculus and derivations and examples you need.

IMPORTANT: I will assign a few worked examples per chapter from Dr. Radi.  You will need to write out the problem in your notebook, try it, then watch Dr. Radi solve the problem and correct your notebook work.

This is a collection of  A LOT of help videos I have found over the last few years organized by chapters.

IMPORTANT: In addition to Dr. Radi’s videos, you are required to watch at least two other help videos per chapter and write a half page summary of each help video in your notebook for that chapter.
