I’ve been watching 3Blue1Brown’s Essence of Linear Algebra series and have been confused a lot by the visualization of transformations of space. I understand somewhat what it represents, but the idea that is being expressed makes more sense numerically, like how the transformations change a vector. That kind of seeing how everything is visually doesn’t help me grasp the concept as much as seeing, for instance, a formula on how to represent that change. When he showed the matrix multiplication as a formula like function composition, that made more sense than just seeing how the vectors change. So is it strange that these concepts seem a little foreign when shown visually, even though that’s just what the numbers are representing?
