sum from x=0 to infinity of x(x)

x = 0 \sum \infty x (x)

diverges

Solution steps

x = 0 \sum \infty xx

Simplify

xx : x^{2}

= x = 0 \sum \infty x^{2}

Apply Series Divergence Test:

diverges

= diverges

n = 1 \sum \infty cos (\frac{20}{n})

n = 1 \sum \infty 5 - 6 (0.7)^{n}

n = 1 \sum \infty \frac{5}{2 n + 1}

n = 1 \sum \infty 3 n e^{- n}

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