sum from n=0 to infinity of n/(1+n^4)

n = 0 \sum \infty \frac{n}{1 + n ^{4}}

converges

Solution steps

n = 0 \sum \infty \frac{n}{1 + n ^{4}}

Apply Series Comparison Test:

converges

= converges

n = 1 \sum \infty \frac{n !}{8 ^{n}}

n = 3 \sum \infty n^{- 0.9999}

n = 2 \sum \infty (- 0.85)^{n}

n = 0 \sum \infty \frac{1}{( 3 n + 1 ) ^{3}}

n = 0 \sum \infty (- \frac{6}{7})^{n}
