I am trying to perform some calculus involving the function $f(x) = \sin(x)/x$ in Sage. This function has a removable sigularity at the origin. Is there a way that I can "modify" the function in Sage to set $f(0) = 1$ while preserving the ability to do things like symbolically differentiate it?

The general answer is to write your own symbolic sinc function. See the symbolic functions wiki page on trac for how to do this and lots of example tickets.
