I am pretty sure that is due to the fact that taylorseries doesn't extract such coefficients correctly when f is given explicitly. Obviously the coefficients 3 of x and a of y are lost. Chapter 3 Power Series Solutions of ODEs and Frobenius Series 3.1 Introduction This chapter is devoted to the research of approximate solutions of nonlin. Such a Taylor-Expansion may be written (see textbooks of calculus, x and h are vectors) f = Sum )^j f, , 2] An example of a Taylor polynomial of a function of three variables: Compare with Mathematica's Series command. Why Mathematica doesn't haveĪ TaylorSeries function is something I've wondered about for years. See that in action with sin(x) and its Taylor polynomials. Necessary to use the procedure Daniel describes, since Series does itsĮxpansion sequentially in the variables. The larger the degree of a Taylor polynomial, the better it approximates the function. In order to to a multi-variable Taylor series expansion, it's So, the code should take ( B C) as an input and then apply the Taylor expansion two times. In a recent thread ( ) the question of linearization of a multinomial was posed.įrank Kampas pointed out that Series has its drawbacks and that something like a Taylor-Series is missing. I totally agree with the sentence 'matrices of infinite dimensionality or for some generators of a Lie algebra etc.' For example, I want to finally write the Taylor expansion of ( I B C) 1.
