VMK in this section are focused on analyzing and working through the mathematic formulae used to perform particular tasks. The main branches of mathematics used in these VMK are Algebra, Geometry, and Calculus. Each VMK will step you through the derivation and required calculations.1 ## Lines in 2DFree 7 min0 8.0 In this video I explain how lines can be drawn in 2D and their general mathematical equation. | 2 ## ParabolasFree 4 min0 5.8 In this video I explain the general equation used to define a parabola in 2D. | 3 ## Perpendicular in 2DFree 7 min0 11.7 This VMK shows you how to find a perpendicular line to a reference line. The reference line can be defined as two points or an equation. |

4 ## Normals in 3DFree 6 min0 15.5 You will be shown how to calculate the normal to a surface defined in 3D. | 6 ## Unit CircleFree 10 min0 9.3 In this VMK I show you how to calculate the (X,Y) coordinates for points located on a circle. I also briefly discuss the difference between degrees and radians. | |

9 ## Rolling Ball using Quaternion Equations15.8 MB 21 min15.8 15.8 Using the arrow keys, you can control a rolling ball on the screen.
