Taylor series technique
Hi everyone,
Is there a certain technique or a program for converting Taylor expansion to summation notation form and vice versa. Example: 1 + x + (5/4)x^2 + (7/4)x^3 +...+O(x^4). I am looking for general approach for rewriting expansions like this in sigma notation.
$\sum f^{(n)}(x_0)*\frac{(x-x_0)^n}{n!}$
