Question # 2. (2 marks) Show that the ratio test fails to apply to the series, 7-n+(-1)", but that the root test does apply. Use the root test to determine if the series converges or not. n=0 Question # 3. (3 marks) Consider the power series, f(x) = į an(x + 1)". Suppose we know that f(-4), as a series, diverges, while f(2) converges. Determine the radius of convergence of the power series for f'(x). Precisely name the results we...

6. For each series: • Use the specified test to deduce the convergence or divergence of the following series. • If the test does not apply, explain why. Then use another test, that does aid in deducing if the series con- verges or divergesc All properties for each test must be formally stated/proved for the specified test. For example, if a test requires the corresponding sequence be decreasing, you must show why this is true. If...
Use the Ratio Test to determine the convergence or divergence of the series. If the Ratio Test is inconclusive, determine the convergence or divergence of the series using other methods. (If you need to use coor-69, enter INFINITY OF-INFINITY, respectively.) 3 ni lim x Your answer cannot be understood or graded. More Information 2 converges diverges
I need help with problem #9
For Questions 5 through 7, determine convergence or divergence of the series using any test of your choice. If the series is geometric, give its sum. You must verify that all assumptions of the test you choose are satisfied. 5. (8 points) § (193) 6. (10 points) { $s 8.
