Geometry of a Tetrahedron: Question 1: Calculating Area with Cross Products

avatar

▶️ Watch on 3Speak


In this video I go over Question 1 of the Discovery Project: Geometry of a Tetrahedron. In this question, we are asked to show that the 4 vectors pointing away from the tetrahedron and with lengths equal to the area of the opposite facing triangles all sum up to equal the 0 vector. In solving this question, I calculate the vectors as cross products, and their lengths as half the length of the cross products. However, for the direction of the resulting cross product vectors, I ensure they are indeed in the direction opposite of the triangular face, so I make the vector components positive or negative accordingly.

This video was taken from my earlier video listed below:

Hi friend, thanks for educating us and teaching us the interaction of the vectors involved in the geometry of a tetrahedron.

Regards

Hi Mathew, let me thank you for the support you have shown on my post featuring a video on about how to store NFTs as pixel art that scales a thousands years, this document explain what it can avoid facing AI threaths of details recognition and profile assessment and also why it features yet a high quality visual potential yet even if it stays low-weight images, it explains everything and it might well be made especially for your interest and curiosity you've shown to pixa's system. https://github.com/pixa-pics/pixa-pics.github.io/blob/main/1000%20Years%20ready%20NFTs%20-%20Handbook.pdf

Wow that is interesting! Sounds like a great idea to store images for the long term and still be upscaled without quality loss! wow!
