How to Do L’Hopital’s Rule?

Identify the limit and substitute the point directly

Check whether the result is an indeterminate form such as 0/0 or ∞/∞

If it is not an indeterminate form, do not use L’Hôpital’s Rule

Differentiate the numerator

Differentiate the denominator

Form the new limit using the derivatives

Evaluate the new limit

If the new limit is still 0/0 or ∞/∞, repeat the process

Stop when the limit is no longer indeterminate or when the limit is found

Verify that the conditions for L’Hôpital’s Rule are satisfied
