Maxima by Example: Ch. 7, 8, 9, 10, and 11 posted

The old chapter seven has been split into 7 plus 10 for ease of maintenance.
However, all (7 - 11) have been updated with a fancy verbatim environment
plus the latex color package to make the maxima code stand out better.
(ch. 1 - 6 remain to be updated with this style.)

New material is:
ch. 8: numerical integration,
ch. 9: bigfloats and arbitrary precision quadrature,
ch. 11 fast fourier transforms
=============

Chapter 9: Bigfloats and Arbitrary Precision Quadrature
(A valuable feature of a computer algebra system is the ability to easily
do arithmetic to "arbitrary" precision. This chapter presents three
powerful methods of arbitrary precision quadrature, including examples
and test integrals.)

Chapter 11: The Fast Fourier Transform.
(Our Maxima package qfft.mac provides a list-based interface to Maxima's 
fft.lisp.
Of particular interest is flines(...) which goes from a signal sample list 
to a FFT
spectrum histogram in one step.)

Chapter 11 Topics:
1. FFT Spectrum of a Monochromatic Signal,
2. FFT Spectrum of a Sum of Two Monochromatic Signals,
3. FFT Spectrum of a Rectangular Wave,
4. FFT Spectrum Sidebands of a Tone Burst Before and After Filtering,
