23. Intro to Derivatives & Area Under the Curve

Evaluate $\lim_{n\to\infty}a_{n}$ and determine whether the sequence converges or diverges.

$a_{n}=5\cos\left(\frac{14}{n^2}\right)$

Evaluate $\lim_{n\to-\infty}a_{n}$ and determine whether the sequence converges or diverges.

$a_{n}=300\sin\left(\frac{n^2-120}{n}\right)$
