Properties of Limits
Examples (1) (2)
1.Direct Substitution This should always be the first choice. Example: Find Once you use the direct substitution technique and get zero in both numerator and denominator (0/0), you have an indeterminate form.
2. Cancellation Examples: (1) (2)
3. Rationalizing the Numerator and Denominator Examples (1) (2) 1-(1+x) = -x
