The technique is called lhopitals rule, and it applies to limits in indeterminate form, such as 00 form or 11form. The limits are defined as the value that the function approaches as it goes to an x value. We describe indeterminate types by evaluating the limit of pieces by plugging in a and writing the resulting symbols, for example, 1 1. Identify limits of determinate forms and indeterminate forms of the type.

The use of lhospitals rule is indicated by an h above the equal sign. If the expression obtained after this substitution does not give enough information to determine the.
