Question

My last Calculus II problems (2 problems)

Answer 1

for the first one, use the ratio test

Answer 2

Well I do know it diverges

Answer 3

the first one doesn't always diverge since we have an x in the series, using the Ratio test can help you figure out which x values will cause the series to converge

Answer 4

I need help step by step

Answer 5

find the interval of convergence, then test the end points; this will establish conditions for absolute and conditional convergence requirements
