Following function is important in applied mathematics and physics (probability theory and statistics, thermodynamics, etc.) and fits our present discussion.


Regarding it as a typical case of a special function defined by an integral that cannot be evaluated as in elementary calculus, do the following.

It can be shown that erf (∞) = 1. Confirm this experimentally by computing erf x for large x.
