- Real Analysis I must determine if the two series below are divergent, conditionally convergent or absolutely convergent. Further I must prove this. In other words, if I use one of the tests, like the comparison test, I must fully explain why this applies. a) 1-(1/1!)+(1/2!)-(1/3!) + . . . b) (1/2) -(2/3) +(3/4) -(4/5) + . . .

Step 1 Recall the Ratio Test, which states that if a, is a series with nonzero terms, and lim 1, or lim =o, then diverges For any fixed value of x such that x = 0, let a (4x)" (3n)1 and find lim 918 (4x)+1 lim (3(n + 1))! = lim (4x) (an) lim (4x)+1 518 (3(n-1))!

Assuming that it converges at x = 5 and diverges at x = -15, answer the following questions. No need for explanations here, but a picture of the interval may help you out. (a) For what values of x it is guaranteed that the series converges? (b) For what values of x it is guaranteed that the diverges? (c) How big and small could the radius of convergence possibly be?arrow_forwardCalculus IIarrow_forward
