• Most links are to Maple or to files in Adobe portable document format (name.pdf). Printing these files is a bit tricky because of differences between printer and screen resolution. It is usually a good idea to magnify the file before printing. Maple sheets are Maple notebooks in Maple 5.0 for the most part. Those with Maple 5.1 should find that the new version is fully backward compatible.

Instead, identify the logical weak spots and then see if you can find some reason to think that despite the gaps in the logic, the ultimate conclusion might nevertheless hold. This sort of thinking is called heuristic thinking, and though it's no substitute for a proof it's a start. Many proofs are found by thinking along heuristic lines to start with.] 4[same as with 2], 5, 6, 10, 11. AND p 118 section 1.10 problems 1,2, 5a.
