Closes this module. Within its interval of convergence, the derivative of a power series is the sum of derivatives of individual terms: [Σf (x)]'=Σf' (x). See how this is used to find the derivative of a power series. This is the currently selected item.

Any polynomial can be easily expressed as a power series around any center c, although most of the coefficients will be zero since a power series has infinitely many terms by definition. f ( x ) = 3 + 2 x + 1 x 2 + 0 x 3 + 0 x 4 + ⋯ {displaystyle f(x)=3+2x+1x^{2}+0x^{3}+0x^{4}+cdots ,}.

In this example the root test seems more appropriate. So, So, since L = 0 < 1 L = 0 < 1 regardless of the value of x x this power series will converge for every x x. In these cases, we say that the radius of convergence is R = ∞ R = ∞ and interval of convergence is − ∞ < x < ∞ − ∞ < x < ∞ .

One way to write our power series is then, Notice as well that if we needed to for some reason we could always write the power series as, All that we’re doing here is noticing that if we ignore the first term (corresponding to n = 0 n = 0) the remainder is just a series that starts at n =1 n = 1.
