Hello mathgroup.
I want the coefficients list of the 3rd order Taylor expansion of Cos[x]:
N[CoefficientList[ Normal[Series[ Cos[x],{x,0,3}]],x]]
This gives me
{1., 0, -0.5}
Note that the coefficient of the 3rd order term, being zero, is missing.
N[CoefficientList[ Normal[Series[ Cos[x],{x,0,4}]],x]]
gives:
{1., 0, -0.5, 0, 0.0416667}
What should I do against missing zeroes at the and of the List?
Please reply to janita at cv.ruu.nl
Thank you!
