I get the following error message:
I added the "..." manually for this post.
Obviously I make a severe problem in getting the numerical solution of this simple equation. Maybe you can help me in getting a numerical solution for an equation.
Btw. I get the same error message when I try the example given in the sage tutorial on page 14 ([[s[p].n(30),.....)
Thanks in advance!
It helps to go step-by-step. In this case, the error message "unable to convert x (=x) to an integer" is telling you that something is a symbolic variable (x) which you're trying to treat as something else:
Looks good, now we can solve:
and you see that sol isn't a dictionary, it's a list of dictionaries. So sol[x] can't work, because it's trying to take the "x-th" element of the list, when really you want one of the entries (0 or 1, as Python/Sage starts counting from 0 instead of 1):
Does that make sense?
