Update July 21
The update for July 2021 includes many new examples and also a notes version to download.
I frequently use colour and highlighting in my explanations when doing worked examples with a class. It can be helpful in Mechanics, for example when taking moments.
I have added this image to my presentation, Colour in Mathematics or pdf version, Colour in Mathematics.
