- 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].

The inverse function that is used to represent the solution gives only one of the solutions to this equation. This equation has an infinite number of solutions:
Solve[x + E ^ x == 1, x]
Other solutions to this equation can be constructed by adding multiples of Pi:
(Sin[x] == b) /. {{x -> ArcSin[b]}, {x -> ArcSin[b] + 2Pi}, {x -> ArcSin[b] - 8Pi}}
