Webb2 Answers. sec ( π 2) is not defined, so any expression that uses it is undefined. Alpha is pattern matching, using sec − 1 ( sec ( x)) = x, which is true for most x. It is often sloppy on cases like this. Ross is correct. To expand, Wolfram is probably doing something like this: It notices that you are calling f − 1 ( f ( x)).
