So, I have Maple 9.5 and 10, and I've just recently begun Harnessing the Power of Mathematics (tm). I love how easy the data entry is, and especially how fun the graphics are, as compared to Mathematica (not that the Wolfram product is bad!). My question is: Can anyone recommend a good book of projects, exercises, etc. for the serious beginner? mizalaina already knows about my obsession with complex numbers.
