Calculus
In calculus even more than other areas, Mathematica packs centuries of mathematical development into a small number of exceptionally powerful functions. Continually enhanced by new methods being discovered at Wolfram Research, the algorithms in Mathematica probably now reach almost every integral and differential equation for which a closed form can be found.
D () partial derivatives, of scalar or vector functions
Dt total derivatives
Integrate () symbolic integrals in one or more dimensions

Series power series and asymptotic expansions »
Limit limits

DSolve symbolic solutions to differential equations
Minimize, Maximize symbolic optimization

Sum, Product symbolic sums and products

Normalize, Orthogonalize normalize, orthogonalize families of functions

Derivative symbolic and numerical derivative functions
DifferentialRoot general representation of linear differential solutions
