I was a TA for that course last semester. I think the actual reason calculus is a prerequisite is just so that students will have some mathematical maturity beforehand. We didn't really teach any concepts that actually used calculus (that I remember).

That said, I totally agree that calculus is good to know for a CS student.

Oh, you do use calculus, at least in the notes, actually touching on the topics I mentioned, so it's a good illustration. For example in the chapters about generating functions and on sums and asymptotics:
