Hiya, Probably I am just doing something wrong ... I have a cubic polynomial p(x) with "regular" coefficients and I wanted coefficients around e.g. (x-1). So I did p1=p.taylor(x,1,3). I get:
x |--> 0.085*(x - 1)^3 - 0.255*(x - 1)^2 + 0.34*x + 1.23 The polynomial is correct, but look at the last two terms. The 1-degree term is in x not in (x-1) and the difference has been added to the 0-degree term. I think i should get: x |--> 0.085*(x - 1)^3 - 0.255*(x - 1)^2 + 0.34*(x-1) + 1.57 See (scroll all the way to the bottom): http://sage.math.canterbury.ac.nz/home/pub/237/ Thanks for any help.
