sum from n=0 to infinity of (2n)/(1+n^4)

n = 0 \sum \infty \frac{2 n}{1 + n ^{4}}

converges

Solution steps

n = 0 \sum \infty \frac{2 n}{1 + n ^{4}}

Apply the constant multiplication rule:

\sum c \cdot a_{n} = c \cdot \sum a_{n}

= 2 \cdot n = 0 \sum \infty \frac{n}{1 + n ^{4}}

Apply Series Comparison Test:

converges

= 2 converges

= converges

\int p (p + 2)^{5} d p

(sin (18 x))^{3}

\frac{d}{d x} ((4 - 3 x)^{9})

\frac{\partial}{\partial x} (z^{2} e^{x} cos (y))

y = (x^{3} + 2)^{2} (x^{5} + 4)^{4}
