CoefficientRules[poly, {x_1, x_2, ...}] gives the list {{e_11, e_12, ...} -> c_1, {e_21, ...} -> c_2, ...} of exponent vectors and coefficients for the monomials in poly with ...

PossibleZeroQ[expr] gives True if basic symbolic and numerical methods suggest that expr has value zero, and gives False otherwise.

Quotient[m, n] gives the integer quotient of m and n. Quotient[m, n, d] uses an offset d.

Real is the head used for real (floating-point) numbers.

PiecewiseExpand[expr] expands nested piecewise functions in expr to give a single piecewise function. PiecewiseExpand[expr, assum] expands piecewise functions using ...

Sec[z] gives the secant of z.

Tan[z] gives the tangent of z.

For many kinds of practical calculations, the only operations you will need to perform on polynomials are essentially structural ones. If you do more advanced algebra with ...

Evaluating integrals is much more difficult than evaluating derivatives. For derivatives, there is a systematic procedure based on the chain rule that effectively allows any ...

GUILoad[src] loads an interface definition and returns immediately with a GUIObject result.GUILoad[src, args] passes arguments to the interface definition.
