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

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

converges

Solution steps

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

Apply Series Comparison Test:

converges

= converges

n = 1 \sum \infty sin^{n} (7)

n = 0 \sum \infty 6 (\frac{1}{7})^{n - 1}

n = 0 \sum \infty 2^{- n - 1}

n = 2 \sum \infty n^{3}

n = 0 \sum \infty \frac{n}{10 n ^{2} + 1}
