X N X X X N - The law that x m x n = x m+n. With x m x n, how many times do we end up multiplying x? First m times, then by another n times, for a total of m+n times. In mathematics, a power series (in one variable) is an infinite series of the form where an represents the coefficient of the n th term and c is a constant called the center of the series. + (n, n) a 0 b n here (n,k) is the binary coefficient = n! For example, the geometric series โ n = 0 โ x n โ n = 0 โ x n converges for all x in the interval (โ1, 1), (โ1, 1), but diverges for all x outside that interval. We now summarize these three.
