Question: Generating functions are useful in studying the number of different types of partitions of an integer n. A partition of a positive integer is a way to write this integer as the sum of positive integers where repetition is allowed and the order of the integers in the sum does not matter. For example, the partitions of 5 (with no restrictions) are 1 + 1 + 1 + 1 + 1, 1 + 1 + 1 + 2, 1 + 1 + 3, 1 + 2 + 2, 1 + 4, 2 + 3, and 5.

Show that the coefficient p(n) of xn in the formal power series expansion of 1/((1-x)(1-x²)(1-x³)···) equals the number of partitions of n.
