2. Prove that the infinite series Ex=1(-1)k diverges. (Hint: Compute the first few terms of the sequence of partial sums and determine a formula for the nth partial sum, Sn. Using this, give a formal proof, starting with the definition for divergence of this series. (Additional reference: Workshop Week #7)

(1 point) Consider the series an where an = (-1)" Find the sum of the first four terms of the series. 84 = 0.97188 !!! (Remember that you can make Webwork do your calculations for you!) Using the alternating series error estimation theorem, find a bound for the magnitude of the error in the above estimation. The absolute value of the difference between 84 and the entire sum is at most: Using your above answers, the value of the entire...
