R2 – Geometry and Trigonometry
Discover how Wave Numbers use angles, radians and trigonometric functions.
R3 – Multiplication – Dot Product
Dot product multiplication in R3 uses the same approach as in classical mathematics. The dot product of the points and is written as and is given by the formula where a flip () precedes the Counters when the Opposite Value is or : For example: Euclidean Geometry Wikipedia describes dot product as follows: […]
R3 – Multiplication Use of Trigonometry
This post covers the use of trigonometry in R3 multiplication. It also describes a trigonometric formula for multiplication. Finding the angles φx, φy and φz R3 multiplication uses trigonometry when it uses the cosines of the angles φx, φy and φz in the multiplication formula later in this post. The following is a description of […]
