L’Hôpital’s Rule and Indeterminate Forms | AP Calculus AB

Worked examples, fresh practice, captions, and corrected transcript: https://calculus.mrwittman.com/10-9-2... Check a quotient’s limiting form, use separate derivatives for valid indeterminate limits, recheck before repeating the rule, and read a needed derivative from a graph.
