  • Calculating Limits Using the Limit Laws

    • Limits of functions can often be determined using simple laws, such as L'Hôpital's rule and squeeze theorem.
    • In this atom, we will study two examples: L'Hôpital's rule or the squeeze theorem.
    • Let $f$, $g$, and $h$ be functions defined on $I$, except possibly at $a$ itself.
    • Suppose that for every $x$ in $I$ not equal to $a$, we have $g(x) \leq f(x) \leq h(x)$, and also suppose that $\lim_{x \to a} g(x) = \lim_{x \to a} h(x) = L$, then $\lim_{x \to a} f(x) = L$.
