Day 8 of the stream, a crash course in trigonometry and why it’s important in matrix multiplication.
I backpedaled on my decision of showing implementation first and explain later.
We to start from a healthy dose of very practical theory with Trigonometry, and introduce the actual scalar guts of matrix operations. This prepares the ground for the next stream, where all of this will be applied.
For more and more specific math learning I can’t recommend Khan Academy warmly enough, which also happens to be free.
