sum from n=2 to infinity of (-1)^n 1/n

n = 2 \sum \infty (- 1)^{n} \frac{1}{n}

converges

Solution steps

n = 2 \sum \infty (- 1)^{n} \frac{1}{n}

Apply Alternating Series Test:

converges

= converges

\int \frac{1}{5 x + x ^{2}} d x

x \to + 0 lim (x ln (x))

f (x) = x + 5, (4, 3)

\frac{d}{d x} (25 - x^{2} - y^{2})

f (x) = \frac{x ^{2}}{x + 8}, (1, \frac{1}{9})
