This video intends not only to give an insight on a visual way of proving that Pythagoras theorem applies to more than the 2 dimensions we most commonly know of it in, but also, the video intends to give a visual representation of how we can start just by using Pythagoras in 2D to derive the general equation of a sphere. Sounds mad right? Hope you enjoy!

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.

Don’t be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry (“trig” as it’s sometimes called) has something to do with triangles. You would be right!
