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 \(\lim_{x \to a} f(x) = f(a)\).

Derivative: \[f'(x) = \lim_{h \to 0} \frac{f(x+h) - f(x)}{h}\].
