sum from n=4 to infinity of 1/((n-4)!)

n = 4 \sum \infty \frac{1}{( n - 4 ) !}

converges

Solution steps

n = 4 \sum \infty \frac{1}{( n - 4 ) !}

Apply Series Ratio Test:

converges

= converges

\frac{d}{d t} (t^{2} + \frac{2 t}{t} - \frac{1}{t ^{2}})

\int \frac{12}{1 + x ^{2}} d x

\frac{d}{d θ} (- 10 sin (θ))

y = c cos (t) + t^{2} sin (t)
