The kind of linear algebra needed for game programming doesn't need calculus to apply. Occasionally calculus is useful in knowing the derivation of the formulas you use, but if you don't care about doing all the proofs behind the applications you can ignore it. However, many college level linear algebra courses go beyond the simple level necessary for doing 3D graphics. For example, when your vector space isn't R[sup]3[/sup] or R[sup]4[/sup] but a function space, you'll need calculus just to normalize your basis vectors. Not highly useful in game programming, but necessary for the kind of math courses that linear algebra is itself a prerequisite for in college.
