2018-12-16 18:54:53 +0200	asked a question	Riemann map between two different domains Sage has the RiemannMap functions which allow you to plot the Riemann map from a circle to a domain. Is there a way to compose two of these to plot the Riemann map between two different arbitrary domains?

2014-08-13 19:57:09 +0200	asked a question	Sinc function 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?
2014-08-13 19:06:57 +0200	asked a question	Defining a function of vector variables I would like to define a Sage function that takes a vector variable and computes the result of some vector function on it, something like `f(v) = v.dot_product(vector((1,1)))` However, when I try to run this in Sage, I get `AttributeError: 'sage.symbolic.expression.Expression' object has no attribute 'dot_product'` Is there a way to achieve this effect in Sage?
