sum from n=0 to infinity of n/((2n+1)!)

n = 0 \sum \infty \frac{n}{( 2 n + 1 ) !}

converges

Solution steps

n = 0 \sum \infty \frac{n}{( 2 n + 1 ) !}

Apply Series Ratio Test:

converges

= converges

f (x) = 9 x^{2} - x^{3}, at x = 2

\int e^{2} sin (x) d x

\int_{0}^{3} 3 x - 1 d x

y^{^{''}} - 9 y^{^{'}} + 2 y = x e^{x}

\int \frac{x + 2}{4 x - x ^{2}} d x
