The radius of convergence can be determined by evalu-ating the limit R= 1 lim m!1 a m+1 am : Example 1.4. where is the Gamma Function and is the Bessel Function of the First Kind (Szeg 1975, p. 102). Because the radius of convergence of a power series is the same for positive and for negative x, the binomial series converges for -1 < x < 1. The second series . The "binomial series" is named because it's a series the sum of terms in a sequence (for example, 1 + 2 + 3) and it's a "binomial" two quantities (from the Latin binomius, which means "two names"). Before knowing about binomial distribution, we must know about the binomial theorem.

Assuming those are right, then I try both points in the series and both converge, so the interval would be (-INF, 1/2] or (-infinity,0][0,1/2] as you said. #3. 31-34 Use the binomial series to expand the function as a power series.

The second term is . The function PL(cos 0) defined by (B.1.6) and (B.1.7) is clearly a polynomial in cos 0 of degree 4, even or odd in cos 0 according to whether t is even or odd.It is called a Legendre polynomial. The series converges for all real values of x. The reverse can also hold; often the radius of convergence for a generating function can be used to deduce the asymptotic growth of the underlying sequence. The third term is . Let us look at some details. The binomial series looks like this: (1 +x) = n=0( n)xn, where ( n) = ( 1)( 2)( n + 1) n! 3,346.
