InverseFunction

FilledSmallSquare InverseFunction[f] represents the inverse of the function f, defined so that InverseFunction[f][y] gives the value of x for which f[x] is equal to y.

FilledSmallSquare For a function with several arguments, InverseFunction[f, n, tot] represents the inverse with respect to the n argument when there are tot arguments in all.

FilledSmallSquare In OutputForm and StandardForm, InverseFunction[f] is printed as .

FilledSmallSquare As discussed in Section 3.2.7, many mathematical functions do not have unique inverses. In such cases, InverseFunction[f] can represent only one of the possible inverses for f.

FilledSmallSquare Example: InverseFunction[Sin] LongRightArrow.

FilledSmallSquare InverseFunction is generated by Solve when the option InverseFunctions is set to Automatic or True.

FilledSmallSquare See Section 2.2.1, Section 2.2.9 and Section 3.4.2.
