- In the case of a single transformation, (0,1) corresponds to the first row of the matrix, and (1,0) corresponds to the second row of the matrix.
- When looking at the vector to be transformed, you can get an idea by looking at that point, right?
- For rotation vectors, you can see that sinθ and cosθ directly correspond to (1,0). https://www.youtube.com/watch?v=ussxCQH9uz4
