Final answer:
L'Hôpital's rule calculator with steps is used to evaluate limits involving indeterminate forms using derivatives, which are a fundamental concept in calculus.
Step-by-step explanation:
L'Hôpital's rule calculator with steps is used to evaluate limits involving indeterminate forms by utilizing the principles of derivatives. L'Hôpital's rule states that if the limit of the quotient of two functions, as x approaches a point, is in an indeterminate form like 0/0 or ∞/∞, then taking the derivative of both the numerator and denominator and evaluating the limit again may provide a valid result.
