Mathematics in 20th Century)
Mathematics in the 20th century tends to be unified from the period of diversity in mathematics in the 19th century. The basis of mathematics in the 20th century is set theory. On the one hand, on the basis of the set

A function mathematically can have an infinite number of function columns converge to this function, then the program approximation implementation can have countless kinds of algorithms, square root nature is no exception.Do not know how many people

There is a formula in chemistry and mathematics that is often used by many people, and that is the square root. Many friends in the use of Word will not enter the "root", indeed this is a difficult problem, this humble little symbol once baffled

Evaluate the square root of N. Assume that x 0 = 1 is the predicted value. Then, calculate the X1 according to the following formula, then substitute X 1 into the right of the formula, and continue to obtain the X2... After an effective iteration,

Mathematical Analysis
1. known functions $ f (x) = \ ln x-Ax $, where $ A $ is a constant. if $ f (x) $ has two zeros $ x_1, x_2 $. test Certificate: $ x_1x_2> E ^ 2 $.
2. set the equation $ \ SiN x-x \ Cos x = 0 $ in $ (0, + \ infty) $ to

1.1.1 Cartesian coordinate system
In two-dimensional space, the Cartesian coordinate system is defined as two coordinate axes that are Cartesian and marked with unit length. The horizontal axis is called the X axis, while the vertical axis is called

In mathematics,MomentIs, Loosely speaking, a quantitative measure of the shape of a set of points. the "second moment", for example, is widely used and measures the "width" (in a particle sense) of a set of points in one dimension or in higher

The mathematical symbols and Greek letters that often appear in foreign languages are often difficult to pronounce and have to stop and get stuck. Many friends may have encountered this problem. I searched on the Internet and sorted out a list of
