What do Very Fat Elephants have to do with the price of fish? Well nothing really ... as I'm not too sure that anything really affects the price of fish ... but I use Very Fat Elephants to help me remember Euler's formula. And, with this being the Year 11 General Maths course for VCE, we need to make sure we have lots of different ways of remembering things. The video starts by looking at what Planar Graphs are and how we might draw them, and we move on to look at why planar graphs and Euler are linked together. As is normal, the videos I create are entertaining, engaging and educational. Why not watch more at www.maffsguru.com

This maths video has been created for courses which are delivered in Australia but, as Maths is a constant, it is equally helpful for students in the USA, UK and other countries who are looking for good maths videos for both high school and middle school.
