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

Details and OptionsDetails and Options

  • Equations are given in the form .
  • 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]].
