  2. Sec. 8.7: Indeterminate Forms and L’Hôpital’s Rule

  3. Sec. 8.7: Indeterminate Forms and L’Hôpital’s Rule Ex: Evaluate:

  4. Sec. 8.7: Indeterminate Forms and L’Hôpital’s Rule Ex: Evaluate: Limit is going to infinity, degrees of numerator and denominator are the same, so look at the leading coefficients.

  5. Sec. 8.7: Indeterminate Forms and L’Hôpital’s Rule Ex: Evaluate:

  6. Sec. 8.7: Indeterminate Forms and L’Hôpital’s Rule

  7. Sec. 8.7: Indeterminate Forms and L’Hôpital’s Rule Two important points to remember using L'Hôpital's Rule: (1) The Rule only applies to quotients! (2) You're finding limits, not derivatives!

  8. Sec. 8.7: Indeterminate Forms and L’Hôpital’s Rule Indeterminate form Ex: Evaluate: Direct substitution yields: Before you apply L’Hopital’s Rule, you must (1) show the indeterminate form and (2) explicitly state that it is indeterminate.

  9. Sec. 8.7: Indeterminate Forms and L’Hôpital’s Rule Examples of indeterminate forms: L'Hôpital's Rule may be used only with these indeterminate forms. L'Hôpital's Rule may NOT be used with indeterminate forms like this.

  10. Sec. 8.7: Indeterminate Forms and L’Hôpital’s Rule Ex: Evaluate: Indeterminate You MUST show the indeterminate form – and state that it is indeterminate – before you use L'Hôpital's Rule!

  11. Sec. 8.7: Indeterminate Forms and L’Hôpital’s Rule Ex: Evaluate: Indeterminate Indeterminate

  12. Sec. 8.7: Indeterminate Forms and L’Hôpital’s Rule Ex: Evaluate: This is not in a form to use L'Hôpital's Rule, so rewrite it: Indeterminate

  13. Sec. 8.7: Indeterminate Forms and L’Hôpital’s Rule Ex: Evaluate: Rewrite to fit a usable indeterminate form: Indeterminate Indeterminate
