"Division" antisense word is "and" is our familiar word. For example: 2 3 = 5, from left to right, we are called. So "points", since it is an antonym, put the above equation in turn: 5 = 2 3. Tell an object into two and more objects, this process is analyzed. In general, the analysis object should be consistent with the analyzed object. It is all the numbers. It is a function that is a function. It is a vector, which is a matrix. The summation is the most basic calculation, minus, multiplication in mathematics, except for the sum of it. More advanced power, finger, pair, triangle, calculus, etc., is also a layer of build, most fundamental or this. The simplest, easier to calculate, and the nature is the simplest. Therefore, the basic starting point of the analysis was made. The wonderful analysis is that the more complex object can be divided into a simpler object by analysis. For example, 2 and 3 are simpler than 5. Study 2 properties alone, then study 3 properties, then simply seek, you can grasp 5 properties. Divide complicated things into a number of simple objects, to all break through each simple object, add up, complicated things are also mastered. Analysis is a fundamental thing in Western ideas. Westerners believe that things always have causality, see the results, to analyze the causes. The so-called analysis is to identify a bunch of factors, indicating that the heap factor combines results. Westerners believe that things can always be analyzed. It is necessary to analyze the partial partial part of the synthesis of this whole. A large part of modern science is such a thing. There are a lot of content in college mathematics. The analysis in mathematics must expand meanings, which means that a mathematical object is reasonably representing a number of more simple objects and real-factor coefficients. However, the calculus and linear algebra have each weight. The calculus research is infinite. The sum of endless items is different from poor items. But the sum of endless items cannot be operated, at least not practical. Therefore, I have to think that I have used an end to use the sum of the sum of the poor to approximate, which is approaching. The conditions for approximation are converge, that is Wuyi, Chinese mathematician, said that the calculus approximates this ax, but it is not good. The main research function of the calculus is mainly due to the variation of the variable X due to the change of the variable x. This change is also to be analyzed. When X is turned from X0 into X1, how is Y how Y0 becomes Y1? According to the above statement, "Y1-Y0)" This mathematical object is added to the "change" in a series of relatively simple "change". The mathematician found a sequence of "changing" objects, and one of the head is a linear change amount. Its coefficient is the derivative, which itself is different DY. Mathematics found that when the amount of change in X is infinite, from this endless, convergent "change" object sequence, as long as the first item is cut, the differential DY is the change in the accurate description of Y. I have seen this in a book, Taylor formula is the peak of mathematical analysis. I don't know if it is reasonable. I think it is such a thing. With Taylor formulas, we can arbitrarily calculate a function of a function at a certain point. After all, it's just a real sum. But in order to express Taylor formula, we used a very complex plug-in number. The algebra cannot be simply added as simple as the real number, which can only represent the form of a form. This is what we realized that there are certain special differences in this connection in this connection, so that they can't add together. Therefore, we need to discuss, what is the nature of this object that is different from the different things. This is vector.
