Im reaching a point in programing where I need to create basic shapes which I simply cant since my math skills are very bad. After finding out that the skills required are trigonometry I read a few books. The result was that I couldnt understand any word at all.
What is required in order to understand basic 2D and 3D trigonometry? Calculus? Algebra? Also how long in general would it take for an average person to learn the material. It would be great if you could give me a guide for someone like me who only knows adding, multiplication, division and substracting.
