Study Notes
Integration of Power Series
- The antiderivative of a power series with a radius of convergence R can be found by integrating each term of the series.
- The resulting series has the same radius of convergence R as the original series.
- The constant of integration for the antiderivative is denoted by C.
Taylor and Maclaurin Series
- A power series is a series of the form $\sum_{n=0}^{\infty} a_nx^n$.
- The radius of convergence of a power series is the largest value R such that the series converges for all x in the interval (-R, R).
- The Taylor Series for a function f(x) at x = a is a power series representation of the function, where the coefficients are determined by the derivatives of f(x) at x = a.
- The Maclaurin Series is a special case of the Taylor Series where a = 0.
- The coefficients of the Maclaurin Series are given by the formula $a_n = \frac{f^n(0)}{n!}$, where f^n(0) is the n-th derivative of f(x) evaluated at x = 0. This means that if you can calculate the derivatives of a function at x = 0 for any n, you can find its Maclaurin series.
