[10 points] Write out the rst three partial sums ( s 1 , s 2 , and s 3 ) of the series X n =1 2 n n ! . 6. [10 points] Give an example of an innite series X a n which diverges, even though lim n a n = 0. 7. [10 points] Suppose a series a n has positive terms ( a n > 0) and its partial sums satisfy s n < 54 for all n . Explain why the series must be convergent....
