Vector Cross Products In R

by | March 17, 2017

The contents of this post can also be found at my main website here. I have recently discovered how to compute vector cross products in the statistical programming language R. The very helpful link was from http://stackoverflow.com/questions/36798301/r-compute-cross-product-of-vectors-physics. The last comment of the link mentions using the pracma package for computing vector cross product. To install the… Read more »

Areas Of Parallelograms and Triangles Using Cross Products

by | March 4, 2017

Hello. I have made a new page about using vector cross products and norms to compute areas of parallelograms and triangles. This new page can be found at my main website here. The featured image is from http://study.com/cimages/multimages/16/parallelogram1.png.

Relating Dot Products, Orthogonal Vectors and Cross Products

by | March 1, 2017

This post is about relating dot products and cross products in the mathematical field of linear algebra. We also look at orthogonal (perpendicular) vectors being related to dot products and to cross products. Prerequisites It is assumed that the reader is familiar with the linear algebra concepts of dot products, orthogonal vectors and cross products.… Read more »
