Basic maths for Grasshopper: Degrees to Radians by Xan Maning

This is just a tip for people who are starting out with Grasshopper for Rhinoceros and are not particularly from a math background. There is a primer for maths in Grasshopper written by Rajaa Issa called “Essential Mathematics for Computational Design” which is excellent but it is teaching to a level that is equivalent to A-Level mathematics in the UK. To get the most out of Grasshopper you ideally need to be at this level, especially when working with vectors and going into VB scripting however it is something you can pick up with the help of such great primers.
