As others have mentioned 'calculus' can mean one of five or six classes (I, II, III, advanced, diffyQ, probably more), basic differentiation is not hard, most of calc is some tricks a computer can learn or do better. At least to my knowledge there is no 'theory of calculus' which allows one to solve generic integrals or differentials, calc is as much an unrelated art to comp sci as learning to play chess will help with accounting.
