Got this in my email inbox today from the Cheapskate mailing list (cnet New= s): Free download of MS Mathematics 4.0 (normally about $20). MS says: "Microsoft Mathematics provides a graphing calculator that=20 plots in 2D and 3D, step-by-step equation solving, and useful tools=20 to help students with math and science studies." I don't know how it compares to the calculators I normally use=20 (eCalc, Excalibur, Calc98) but it offers graphing, which the=20 calculators I mentioned don't offer. Its free, at least for now, and I thought that some might find it useful. dwayne --=20 Dwayne Reid Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax www.trinity-electronics.com Custom Electronics Design and Manufacturing --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
