SolveAlways

SolveAlways[eqns, vars]
gives the values of parameters that make the equations eqns valid for all values of the variables vars.

MORE INFORMATION

Equations are given in the form lhsrhs.

Simultaneous equations can be combined either in a list or with &&.

A single variable or a list of variables can be specified.

SolveAlways works primarily with linear and polynomial equations.

SolveAlways produces relations between parameters that appear in eqns, but are not in the list of variables vars.

SolveAlways[eqns, vars] is equivalent to Solve[!Eliminate[!eqns, vars]].
