What to Focus On

  • Indeterminate means unknown.
  • L'Hôpital's Rule uses derivatives.
  • The numerator and denominator are differentiated separately.
  • 0/0 is an indeterminate form.
  • Different 0/0 limits can give different answers.
  • Check the form before using L'Hôpital's Rule.
  • ∞/∞ is indeterminate.
  • Same form can produce ∞, 1, or 0.
  • L'Hôpital's Rule is valid for this form.

Common Mistakes to Avoid

If the numerator approaches 0, the whole fraction must approach 0.

L'Hôpital's Rule can be used for any limit with a quotient.

In L'Hôpital's Rule, the fraction is differentiated as a single quotient using the quotient rule.
