Easy Limits Edit

\lim_{x \to 4} \frac{x+3}{x^2+1} = \frac{4+3}{16+1} Plug in the number as x.

Harder (Derivative) Limits Edit

The difference quotent always gives \frac{0}{0}, and requires cancellation.

Right and Left-Hand limits Edit

\lim_{x \to n^+} indicates right-hand limit

\lim_{x \to n^-} indicates left-hand limit
