There is a variable EMBEDDED_MODE that you need to check. Grep the
source for EMBEDDED_MODE to see how it is used.

Hi,
A short remark. It seems that taking the derivative of an element of a
fraction field is not supported at this point. This feels somewhat
inconsistent (tested with sage 2.10.4)

sage: derivative(x^2,x)
