In some way or another, each looks at elementary functions from the perspective of experimental mathematics.

It is easy to compute for usual elementary functions.

Interval counterparts to continuous elementary functions are easily obtained.

They were also less proficient at the tasks of basic calculus, such as differentiating and integrating elementary functions.

Those who actually manage to register have reported difficulties with elementary functions such as sending email and web browsing.

These are arranged in sessions each focused on a specific objective, among then elementary functions and differential, Cauchy integral formula, and contour integration.

In introducing elementary functions, the authors have followed the presentation given by Ernst Lindelof in his Finnish textbook, Johdatus funktioteoriaan.

Interval counterparts to continuous elementary functions are easily obtained.
