SolveAlways
 Usage
• SolveAlways[eqns, vars] gives the values of parameters that make the equations eqns valid for all values of the variables vars.
Notes
• Equations are given in the form lhs  rhs. • Simultaneous equations can be combined either in a list or with &&. • A single variable or a list of variables can be specified. • Example: SolveAlways[a x + b 0, x]  . • 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]]. • New in Version 1.
