Tangentially related to this discussion but I'm curious what you consider "the fun stuff"? I use linear algebra every day in my work as a graphics programmer.

Tangentially related to this discussion but I'm curious what you consider "the fun stuff"? I use linear algebra every day in my work as a graphics programmer. A huge portion of what I do depends on it. While I frequently need calculus it's still a minority of the time. Derivates obviously show up everywhere: velocity, acceleration, gradients, ... But it seems to me only the narrow portion relating to physically-based rendering or simulation requires an understanding of integrals. At the moment I can mainly think of how it's used to define continuous functions before introducing the discretization used to actually compute them.
