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
The following traceback may be corrupted or invalid
The error message is: ('EOF in multi-line statement', (805, 0))
