Question
(b) If f(x) has a power series representation about a point x = a with radius of convergence R > 0, i.e.
∞
f(x) = Σ c₂(x − a)" for all x € (−R + a, a + R),
n=0
then a power series for f'(x) about the point x = a with the same radius of convergence R can be obtained by
differentiating the power series for f(x) term-by-term, i.e.
00
f'(x) = Σnc₂(x − a)"-¹ for all x € (-R + a, a + R).
n=0
True
False
