f(x,y,z) = x+y+z
x << y << z around 0
I would like the first order Taylor expansion of f around 0. And I would expect this result:
>> taylor(f, (x,0),(y,0),(z,0),1)
z
But I have :
>> taylor(f, (x,0),(y,0),(z,0),1)
x+y+z
How can I do it?rufus_wilsonMon, 18 Aug 2014 22:15:57 +0200https://ask.sagemath.org/question/23821/Multivariate Taylor Serieshttps://ask.sagemath.org/question/9783/multivariate-taylor-series/Hi. I know `f.taylor(x, x_0, n)` would generate an n-order Taylor approximation of f around x_0 for a function of a single variable. How can I do this for multiple variables? I know Maxima can handle it. How do I do this in sage?yktulaThu, 07 Feb 2013 18:13:48 +0100https://ask.sagemath.org/question/9783/
