MATHEMATICA MESSAGE

Solve::ifun Eliminate::ifun SolveAlways::ifun

DetailsDetails

  • This message is generated when Solve and related functions use inverse functions to represent a solution.
  • Inverse functions normally give one branch of a general inverse, so equations that are solved in terms of inverse functions may omit solutions associated with other branches.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[Solve::ifun].
