sum from n=1 to infinity of (17n!)/(n^n)

n = 1 \sum \infty \frac{17 n !}{n ^{n}}

converges

Solution steps

n = 1 \sum \infty \frac{17 n !}{n ^{n}}

Apply the constant multiplication rule:

\sum c \cdot a_{n} = c \cdot \sum a_{n}

= 17 \cdot n = 1 \sum \infty \frac{n !}{n ^{n}}

Apply Series Ratio Test:

converges

= 17 converges

= converges

\int \frac{( y - 1 ) ( y - 5 )}{y ^{3} - y ^{2} + 3 y + 5} d y

\frac{d y}{d x} = - 0.05 y

\int_{0}^{1} π (y^{2} - y^{4}) d y
