How to expand a function into a power series
How to expand \[x^{3}-3x^{2} + x\] into a power series of the form: \[\sum_{k=0}^{\infty} A_{k}P_{k}\]
Do you know a closed-form expression for the sequence \(\{a_n\}\) of coefficients \(\{0,1,-3,1,0,0,0,\dots\}\)?
ooo, did you mean this? http://www.idea.wsu.edu/Quantum/legendre_series.htm
