Thanks David, Tim, Burcin! Correct me if I have missed your points. With your suggestions here is the new conventions for Heaviside and unit step
(2) Heaviside: (a) represented as: "heaviside" (b) latex name : "\theta" (c) heaviside(0): will return symbolic expression "heaviside(0)" (3) unit_step = heaviside (Just an alias) >> Will, for example, sin(t)*unit_step(t) be defined? >> If so, will you provide a plotting and _latex_ method for it? >> > I really hope so. These functions are sub-class of PrimitiveFunctions of new symbolics. So many methods are predefined. For example, I didn't write any code for plotting but it works. Here is a screenshot from my Sage notebook. http://www.math.unb.ca/~ghossain/sage-generalized-functions.png Hopefully, it answers some of your questions. I am still working on integration algorithm.
