Proving mathematical theorems usually involves the proof of
an implication, p --> q. Often it is convenient to prove the implication
by proving one which is equivalent to or "stronger" than the original
theorem. Proofs of this type are called indirect proofs.
In Chapter I five forms of indirect proofs...
An interactive Computational geometry package was developed
for the purpose of experimenting with geometry problems in
the Euclidean plane. The package also contains computer graphics
functions to display the result. Application independent functions
were developed that are both flexible and general enough for
creating new geometry experiments as well as...
The purpose of study was to investigate college algebra students' understanding of function concepts. In addition, their solution strategies and algebraic thinking and reasoning were explored. Twenty-four volunteer students from one college algebra
recitation class participated in the study to access their understanding of functions. Five
out of 24 volunteer...
