Although there are significant dif- ferences among the packages, both in perfolillance and price, all can perfOIm standard algebra and calculus operations. Having a symbolic computation package available can be very useful in the study of approximation techniques. The results in most of our examples and exercises have been generated using problems for which exact values can be deter- mined, since this penllits the perfonnance of...
