Expressions that involve limits that do not directly provide enough information to determine the limit's value are called indeterminate forms. A sample would be when both the numerator and the denominator approach zero. Which can be resolved by factoring, applying the L'Hopital's Rule, simplifying, or by substitution. Another sample is when both the numerator and the denominator approach infinity. Which can be solved using the L'Hopital's Rule, or Algebraic Manipulation. It also appears when a factor approaches zero while another factor approaches infinity. When this occurs there are some techniques that can be used to evaluate the corresponding limits accurately as the initial samples stated
