Principles
The Wave Numbers system comprises of the ^ Opposite Values (called ‘Hat’ Opposites) and the v Opposite Values (called ‘Vee’ Opposites). All the Opposite Values in the Wave Numbers system start from 0.
R3 – Multiplication Links to Rotation and Rotication – Part 1
Introduction: This post starts with a description of long multiplication in R3. It then describes the R3 multiplication links to rotation and rotication and how the different operations move a point. Long Multiplication Calculate (5^ + 7iv + 2j^)*(4v + 6iv + 4jv) = (20^ + 30iv + 66jv) by long multiplication and using the R3 multiplication table. For example: 4v […]
R3 – Return and Orthogonal Rules
Rotation: In this post, we delve into the Return and Orthogonal rules of rotation within the three-dimensional space R3. These principles are foundational to understanding the universal rules governing rotations, especially in contexts like Wave Numbers, where rotation operations play a crucial role. A rotation in R3 involves moving a point from one position to […]
R3 – Rotation Ball
Use a Tennis Ball as a Rotation Prop: A physical prop helps to understand 3d rotation. There are many digital 3d spheres on-line. They limit the user experience as they are only in 2d. It is difficult to find a physical 3d sphere to help with understanding rotation. A major requirement is to be able […]
