Domain of power series
WebExample 1: Find a power series representation of the function x 1 + x 2 , and determine for which x it would be defined. Example 2 : Find a power series representation of the function 1 7 + 2 x, and determine for which x it would be defined. Solution 1: Replace x (in our original f ( x) before the video) by − x 2, and multiply the expression ... WebApr 4, 2024 · A power series centered at x = a is a function of the form ∞ ∑ k = 0ck(x − a)k where { ck } is a sequence of real numbers and x is an independent variable. We can substitute different values for x and test whether the resulting series converges or diverges.

WebYour power series is correct. The binomial expansion gives 1 1 + 5 x 2 ≡ ( 1 + 5 x 2) − 1 = 1 − 5 x 2 + ( 5 x 2) 2 − ( 5 x 2) 3 + ⋯ and so we need 5 x 2 < 1 for the infinite series to converge. Multiplying by x does not change the domain of convergence. When we substitute a value for x, x will just be a finite number.
