PadeApproximant has been added to the built-in Mathematica kernel. EconomizedRationalApproximation is now available in the newly created Function Approximations Package.

NewtonCotesError[n, f, a, b] gives the error in the elementary n-point Newton-Cotes quadrature formula for the function f on an interval from a to b.

The graphics language of Mathematica is fully integrated with dynamic interactivity. This lets you create graphics that can respond to input devices in a variety of ways.

InverseSeries[s] takes the series s, and gives a series for the inverse of the function represented by s. InverseSeries[s, x] uses the variable x in the inverse series.

Following are two examples of nonlinear systems of ODEs that can be solved symbolically using DSolve. The first three equations in this system of four nonlinear ODEs can be ...
