    Understanding L'Hôpital's Rule

    L'Hôpital's rule is a simple yet powerful technique for resolving indeterminate forms of limits. The rule states that for certain types of limits, we can take the derivative of the numerator and denominator separately and evaluate the limit of the ratio of the derivatives. This approach is based on the idea that the limit of a ratio of functions is equal to the limit of the ratio of their derivatives when the limit exists. For example, if we have a limit of the form 0/0, we can try to take the derivatives of the numerator and denominator and see if the resulting limit is well-defined.
