Definitions to Memorize
Definition of Limit:
\(\lim_{x \to a} f(x) = L\) means
that for all \(\epsilon \gt 0\)
there is a \(\delta \gt 0\) such that
\(f(x)  L \lt \epsilon\) whenever \(0 \lt x  a \lt \delta\).
Continuity:
\(f\) is continuous at \(a\) if \(\lim_{x \to a} f(x) = f(c)\).
Derivative:
\[f'(x) = \lim_{h \to 0} \frac{f(x+h)  f(x)}{h}\].
