The next improvement would be to find a recurrence formula for the terms instead of computing them directly. So for example, if summing over c[n] = x**n / n!, instead of computing c[n] = x**n / factorial(n) for each n, you'd compute c[0] and then just do c[n] = c[n-1] * x / n for each of the remaining terms.
