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:
  sine (sin)   cosine (cos)   tangent (tan)
  arcsine (arcsin)   arccosine (arccos)   arctangent (arctan)
  base 10 logarithm (log)     natural logarithm (ln)     exponential with base e (exp or e x )
  square root (sqrt)   power ( y x )
For each of these functions we will:
