L'H?pital studied calculus under the guidance of Bernoulli, a Swiss mathematician, and became a major member of the new French school of analysis. L'H?pital's infinitesimal analysis created an algorithm, namely the Robida's rule, to find the limit of the quotient of two functions that meet certain conditions.
The meaning of L'H?pital's law.
Lobida's law is a method to determine the indefinite value under certain conditions by taking the derivatives of the numerator and denominator respectively, and then finding the limit. Under certain conditions, this method mainly determines the value of infinitive through the derivation of numerator and denominator, and then the limit. Before applying L'H?pital's law, two tasks must be completed: first, whether the limits of numerator and denominator are all equal to zero (or infinity); The second is whether the numerator denominator is differentiable in a limited area; If these two conditions are satisfied, then take derivative and judge whether the limit after derivative exists.
