I am new to sage and I have the following question. Here is a minimal working example:

f=x^2-3*y; f

The output of it is 2*x, but I wonder if there is a way to say to sage that I want to present the output g=2x.

Thanks in advance

Short answer: yes with

print "g = %r" % g

Other short answer: no, you cannot (easily) do that automatically.

Note that you can define g as a symbolic function

sage: g(x,y) = f.diff(x)
sage: g
(x, y) |--> 2*x

If you're working from the notebook you can use the pretty_print function. In your example


will display 2x as rendered LaTeX. I doesn't just typeset mathematics, either: you can also use it to prettify other objects, like long lists or dictionaries. Here's a more interesting example

pretty print the derivative of a function involving tangents and fractions
