I've built a worksheet that I'll use next week to motivate the idea of polynomials approximating more complicated functions. It is very fast- and-loose with the mathematics because I want it to precede our study of infinite series, so any serious tests of convergence are covered by vigorous hand-waving.
I've posted this here as another in my series of experiments creating interactive texts with Sage. This was authored in LaTeX with the eventual worksheet as the end-product. I've produced a PDF from the same source to handout to the students, but of course it won't have the interactivity. If you view the worksheet, there's a bit of screwiness with some of the displayed math (the arctan stuff) which is a result of avoiding a more serious bug in TeX4ht (which should be fixed eventually). This creation still requires one small conversion step with a custom script I wrote. Eventually this step could be eliminated. Caveats: It contains four @interact demonstrations so you can't run it off of sagenb.org and must instead download it from the URL below to run/view locally and get the full effect, or else its liable to look pretty crummy - no interact's and perhaps the jsMath won't get rendered right. It also seems the horizontal axes are expanded when they are first run, so to get the intended plots, try re-evaluating each demonstration. I had a screenshot, but my email attempts to post it keep failing. http://sagenb.org/pub/383/ Rob --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sage-edu" group.
