Cubics
(Built-in Mathematica Symbol) Cubics is an option for functions that involve solving algebraic equations, that specifies whether explicit forms for solutions to cubic equations should be given.
CoefficientArrays[polys, vars] gives the arrays of coefficients of the variables vars in the polynomials polys.
Thread
(Built-in Mathematica Symbol) Thread[f[args]] "threads" f over any lists that appear in args. Thread[f[args], h] threads f over any objects with head h that appear in args. Thread[f[args], h, n] threads f ...

For ordinary polynomials, Factor and Expand give the most important forms. For rational expressions, there are many different forms that can be useful. Different kinds of ...
SolveAlways[eqns, vars] gives the values of parameters that make the equations eqns valid for all values of the variables vars.
When Mathematica cannot give you an explicit result for an integral, it leaves the integral in a symbolic form. It is often useful to manipulate this symbolic form. ...
