Hello, I am completely new to Sage.. but I am so excited, it looks
like the ultimate tool !!!
Unfortunately, I have already big problems from the beginning...
I cannot just plot x^2 ....
here is the kind of error I get ....
any ideas ????
thnaks so much for your help !!
Julien
sage: plot(x^2,(x,300,500))
ERROR: An unexpected error occurred while tokenizing input
