sage: Phi(.1,2/3).n() TypeError: cannot evaluate symbolic expression numerically I don't think sage succeeds in finding a numerical approximation to your infinite sum, even if explicit parameters are filled in. So, even if you were able to overcome the ValueError you're currently seeing, I think you'll need to give sage more hints on how to find numerical approximations to the expression you're giving (for a plot, you'll need numerics in the end). The actual error you're experiencing is, by the looks of it, a failure of the routine that tries to convert a symbolic expression into a recipe that can be used to find numerical approximations quickly. It's probably failing to convert the infinite sum (and by the looks of it, for good reasons, but not particularly because you made a programming error). -- You received this message because you are subscribed to the Google Groups "sage-support" group.
