2014-09-24 Thread Chris Seberino
I read W. Stein's blog on why he thinks Sage is failing since it isn't on par with Maple, Mathematica and other Ma*'s *now*. I teach high schoolers and college students. At that level Sage is more than adequate as a replacement for all Ma*'s now. If it encourages anybody..I think the probl

2011-08-21 Thread Chris Seberino
implicit_multiplication(10) still does not interpret "x (x)" as x^2 but rather as a function call. Rarely do I put a space between the function name and the argument list. It would seem to be a useful new option to allow implicit multiplication that interprets a letter followed by a space and an o
