determine if the series is absolutely convergent and convergent
the sum from n=1 to infinity of
sin(n^2)/n^2
what series test should I use and how?
the ratio test?

sin(n^2)/n^2  < 1/n^2 and sum from 1 to infinity of 1/n^2 converges (to pi^2/6 )

determine if the series is absolutely convergent and convergent. the sum from n=0 to infinity of ((1)^n*e^n)/(n!) I used the ratio test and said that it was absolutely convergent and convergent. is this true?

for the series is absolutely convergent and convergent the series from 1 to infinity of (x^3)/(5^x) i did the ration test and get absolutely convergent and convergent is this correct?

for each series determine if the series is absolutely convergent and convergent the sum from 0 to infinity of (1)^n/(the square root of (n+1)) I did the ratio test and got 1, which is less than 0 making it absolutely convergent, …

please help with calculus thank you!
Is this correct? determine if absolutely convergent and convergent 1. the series from n=0 to infinity of ((1)^n)/n! I said it was abs. conv, and therefore conv 2. the series from n=0 to infinity of (1)^n/(the square root of (n^2+n+1))

Show that the following series is absolutely convergent: Summation from 1 to infinity: [(1)^n * (n+1) * 3^n]/ [2^(2n+1)] I've done the ratio test and replaced n in this series with n+1. I get 3/4 in the end, which is less than 1, …
