Radical problem solver

Radical problem solver can be found online or in mathematical textbooks. For this reason, Newton thought of using Taylor expansion to solve it. The general idea is as follows: Differential equations are developed along with calculus. Newton and Leibniz, the founders of calculus, have dealt with problems related to differential equations in their works. Differential equations are widely used and can solve many problems related to derivatives.

This is the second stage of algebra. The third stage of algebra is the study of panstructures such as categories and functors, which require mathematical researchers to deal with. In general, the magic of algebra is that it has been upgraded from the study of specific objects to the study of the relationship between objects. It has become more abstract, more essential and more capable of depicting. For example, describing the symmetry of crystals requires groups, and characterizing the symmetry of quasicrystals requires groupoids...

He actively participated in kangaroo mathematics competitions in grades 5 and 6, and won gold and silver awards many times. He enjoyed the interesting games in the middle school mathematics class very much. After class, he would also find exercises. If he didn't know how to ask the teacher, he said that mathematics had become a part of his life. Another seventh grade student, pan, confessed that he liked all the knowledge of mathematics, and that mathematics had given him a goal in the future.

If the probability of at least one of several events is required, it can be immediately associated with the probability addition formula; When the event groups are independent of each other, the probability formula of opposing events is used; If an event is accompanied by the occurrence of a complete event group, it can be immediately associated that the probability of occurrence of the event is calculated by the total probability formula; If a complete event group occurs due to its occurrence, it can be immediately associated that the probability of occurrence of the event is calculated by using the total probability formula; The problem of solving the probability that a system composed of several independent random variables with known probability distributions satisfies a certain relationship (or finding the number of random variables with known probability) can be immediately associated with the central limit theorem..
