I'm in the process of uploading all of my Youtube videos to DTube, where they can be recorded on the Steem blockchain. In this video, we work through exam style questions on vectors, lines and plains.

I'm in the process of uploading all of my Youtube videos to DTube, where they can be recorded on the Steem blockchain. In this video, we solve a linear system of equations for 3 planes: 5x + 2y + 11z =

How does SVD reduce the dimension of data? Singular Value Decomposition by itself produces an exact fit. But you can use the decomposed form to find a lower-rank matrix which approximates the original

The height of mountain of Baek-Du is 2770m. It can also be 2.77km. It is depending on the unit you want to use. The fact is, whatever you use 2770 or 2.77, both means Baek-Du's height, whatever you

In this video, we develop the process behind the multiplication of 2 matrices. We discover how we start with one matrix of certain dimensions, multiply it by another matrix of different dimensions and
