Amazing, Life Changing Tutor
Before I met Jonathan, I was struggling through most of my STEM classes because I was simply not studying properly. He taught me all kinds of new study habits that would help me to save time, raise my grades, and lower my stress. Jonathan was specifically tutoring me in vector calculus and is an amazing tutor on the subject. You will walk away from a lesson with a game plan knowing exactly what you need to do before your next session with him or before your next exam in order to do well in the course. I highly recommend him as a tutor.

(i) What is the difference between distance and displacement ? (ii) Can magnitude of the distance be equal to the displacement of the object ? (iii) What are uniform and non-uniform motion ? check out the video for detailed study.

Reviewing big ideas of polar coordinates for the AP Calculus BC exam. Here’s a pdf summary of the slides: https://goo.gl/5JbQaK We go over converting to rectangular; finding a bunch of derivatives; finding area; and related rates. Also I give a list of the most recent polar FRQs. See my other videos for lots more on…
