To show convergence… • bn’s are eventually decreasing • Ex:
Alternating Series Remainder If is a convergent alternating series, then (Error is at most the size of the 1st neglected term)
How many terms of: do you need to sum in order to be sure your approximation is correct to within 2 decimal places?
