Deriving recurrence relations
WebMar 16, 2024 · We can often solve a recurrence relation in a manner analogous to solving a differential equations by multiplying by an integrating factor and then integrating. Instead, we use a summation factor to telescope the recurrence to a sum. Proper choice of a summation factor makes it possible to solve many of the recurrences that arise in practice.
