sum from n=1 to infinity}(\sqrt{n of)/(n^2+1)

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

converges

Solution steps

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

Apply Series Comparison Test:

converges

= converges

f (x) = \frac{8 x}{x ^{2} + 1}, at x = - 1

\frac{d}{d x} (I n (x^{3}))

\frac{d}{d x} ((x^{2} + x^{3}) \cdot (3 x^{4} - x^{3}))

y^{^{''}} - 2 y^{^{'}} + y = t + 1

x \to 0 lim (\frac{1}{0})
