sum from n=1 to infinity of n^{-3/2}

n = 1 \sum \infty n^{- \frac{3}{2}}

converges

Solution steps

n = 1 \sum \infty n^{- \frac{3}{2}}

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

= n = 1 \sum \infty \frac{1}{n ^{\frac{3}{2}}}

Apply p-Series Test:

converges

= converges

\int v^{- \frac{4}{5}} d v

e^{- i x}

\int \frac{3}{( 3 x - 1 ) ln ( 3 x - 1 )} d x

\int sin^{6} (a x) d x

\int cos^{2} (v) d v
