For the next two series, (1) find the interval of convergence and (2) study convergence at the end points of the interval if any. Also, (3) indicate for what values of x the series converges absolutely, conditionally, or not at all. You must indicate the test you use and show the interval of convergence both analytically and graphically and summarize your results on the picture. ∑∞ n=1 ((−1)^n−1)/ (n^1/4)) *x^n
