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.

This is a proof for the power reducing formula for sine and cosine. Super handy when integrating sin^2x or cos^2x. We use the double angle formula for cosine to prove both.

In this video we show how to integrate the volume of a sphere of radius R using spherical coordinates. We enjoy solving common math problems from undergraduate programs throughout examples – it is easy and quick to learn! Stay tuned for more!
