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?
