sum from n=1 to infinity of cos(1/(n^3))

n = 1 \sum \infty cos (\frac{1}{n ^{3}})

diverges

Solution steps

n = 1 \sum \infty cos (\frac{1}{n ^{3}})

Apply Series Divergence Test:

diverges

= diverges

\int 15 x^{2} (x^{3} - 1)^{4} d x

- 15 x^{4} + 270 x^{2}

\frac{d}{d x} (5 e^{6 x})

\int 8 x^{3} e^{- x^{2}} d x

y^{^{'}} = y (x y^{4} + 2)
