2010-09-06 Thread Michael Beeson
I want to create a vector space of dimension three, over the field whose elements are symbolic expressions. (The reason is that then I can do vector calculus on such objects, which represent surfaces in 3- space if the expressions depend on 2 parameters.) How can I do this? The following,
