How to solve recursive equations
WebDefine A ( z) = ∑ n ≥ 0 a n z n. Rewrite your recurrence without subtractions in indices: a n + 2 = − 4 a n + 1 − 4 a n. Multiply by z n, add over n ≥ 0, and recognize the resulting sums: A ( z) − a 0 − a 1 z z 2 = − 4 A ( z) − a 0 z − 4 A ( z) By running the recurrence backwards, you have a 0 = − 1, and: A ( z) = 2 ( 1 ...

WebRecursion has many, many applications. In this module, we'll see how to use recursion to compute the factorial function, to determine whether a word is a palindrome, to compute powers of a number, to draw a type of fractal, and to solve the ancient Towers of Hanoi problem. Later modules will use recursion to solve other problems, including sorting.
