Description (last modified by )
I think an error should be raised in the following example:
sage: f(x) = x**(1/3); f x |--> x^(1/3) sage: f.taylor(x,0,3) x |--> x^(1/3)

Replying to kcrisman:
I'm not familiar with this notation for Taylor polynomials (which is surprising) but anyway to make it clear:
f.taylor(x,0,3) x |--> x^(1/3)For what it's worth,
f.series(x,3)
gives an error.
