Maple can factor polynomials. Maple uses the abs command for absolute value. Solve can also handle systems of equations. The erf function is the error function. The sum command is quite useful.
Maple is good at taking limits.
So y approaches e, the base of the natural logarithms, as x approaches infinity. Let's consider this harmless-looking function. The diff command gives the derivative of f with respect to x. The indefinite integral of fp is a function whose derivative is fp. Here is another indefinite integration.
