This chapter is the first of the series that addresses some of the numerical techniques used. Numerical integration is very useful in situations where an exact solution to an integration problem cannot be found analytically.

The techniques described are the Midpoint, Trapezoidal and Simpson's rules. A comparison shows that Simpson's Rule is clearly superior to the others.

Associated with this chapter is also a graphical demonstration of the different methods. This is available on the associated diskette and is also accessible over the Internet.
