As per an irc conversation last week, here is a list of math expressions using implicit multiplication. Sorry for the delay:
a b c(a^2 + b^2 + c^2) a b + c^2 == y (z/(2sin(y z/55))+y+x)^(z/(2sin(y z/55))+y+x) 2(x/2)^2+4(2x)^2 0==-16x^2+48x (x+2)(x-1) x^2-4x+4 2(x+3)(x-4) 2x^2-2x-25<=0 -16x^2+132x 2(x+3)(x-4) x^2-5x+4 3(x-5)(x-5) (x-1)(x-2)x (a-b)(a-b)(a-b) Take any usual python expression and drop the multiplication operator (or really make it *optional*). So for example, 2*x would be 2x. However, when ambiguity would result in variable names, use * or a space. For example, a*b*c would be a b c (to distinguish from the variable "abc"). One other thing, I'm not sure if this was fixed in 2.9 but I'm running 2.8.15---the docs say that any single lowercase or uppercase letter is predefined to be a variable. However, typing an expression like "a+c" gives me an error message (name 'c' is not defined). I have to explicitly define every variable except "x". --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://sage.math.washington.edu/sage/ and http://sage.scipy.org/sage/ -~----------~----~----~----~------~----~------~--~---
