This post can also be found at my main website here. Hi. There was an article that I found from here which talks about a 3D printed house costing around $10, 000 which can be made in under 24 hours. The article also mentions the corresponding Youtube video (about 7 min.). This video from a… Read more »
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 »
Hi. I have made a page about cross products in the linear algebra field of mathematics. Cross products are also used in physics. The full contents can be found at my main website here.
