Online Volume 2, Three Skills
for Algebra, Chapters 1 to 25 - skip 18., verbalizes and explains key skills
and concepts, those needed in calculus, again to make the hard easier. A visual
understanding of complex numbers
may serve as back ground info for partial fraction decomposition.

On The Definition of Functions
Functions or rules for calculating them can be introduced or
defined in many ways.
- In algebra, you may have seen the definition of
functions using polynomials, square roots, small powers and
so on.
- In trigonometry, you may see the right
triangle and unit circle definitions of the sine, cosine
and tangent functions. Again, in trigonometry, you may see
the idea of the inverse to a function employed, to define or
introduce the arccos, arcsin and arctan
functions.
- The set theoretic approach to defining a
function is to give a set of ordered pairs with the
vertical line property. Here a finite set of ordered pairs
(with the vertical line property) correspond to a table of
values for a function.
- In previous chapters, a
function g(x) was given, introduced or defined, by the
slope or derivative f¢(x) of another function f(x).
- In this chapter, you have seen a function F(x)
introduced or defined as the area-under-a curve between
two points. For another example, see the definition of the
natural logarithm in the next chapter.
