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. As we all know, the limit of the ratio of two infinitesimals or the ratio of two infinitesimals may or may not exist.
Therefore, when solving this kind of limit, it is often necessary to transform it into a limit algorithm or an important limit for calculation. L'H?pital's law is a general method applied to this kind of limit calculation.
Introduction to L'H?pital's Law:
Lobida's rule is a method to solve the uncertainty in the field of calculus. This method points out that under certain conditions, in order to solve the problem of undetermined value, the numerator and denominator can be derived respectively, and then the limit can be solved. Lobida rule is a common means to determine the uncertainty.
L'H?pital's law was developed by Swiss mathematician johann bernoulli and mathematician Fran? ois Guillaume Antoine L'H?pital (Fran? Marquis Louis Antoine? Pital) introduced this method to the whole world in his published works. In practical application, the limit form that can be transformed into undetermined values to solve problems through mathematical operations is also applicable to Robida's law.
Lobida's rule is an effective method to solve indefinite forms. If it can be flexibly combined with other methods (such as equivalent infinitesimal and important limit formula, Taylor formula, etc.). ), the solution process will be more convenient.
