5.3 - Reference - The eleven built-in functions

Mathematicians have defined literally hundreds of functions. (See the Handbook of Mathematical Functions, by Abramowitz and Stegun, for definitions of many of them.) The eleven most useful functions are built into the Algebra Coach. They are:
  sin   cos   tan
  arcsin   arccos          arctan
  log   ln   exp
