Anonymous users2024-02-04Circumcision: In order to derive the formula for calculating the area of a circle and derive the more precise value of pi, Liu Hui of the Wei and Jin dynasties created the circumcision, which laid a theoretical foundation and provided a scientific algorithm for the research of pi. Circumference:
It is an outstanding creation of the Northern Song Dynasty scientist Shen Kuo in "Mengxi Bi Tan", which gives an approximate relationship between the string, the arrow and the arc length of the bow. Double-difference: The last few problems in the Pythagorean chapter of the Nine Chapters of Arithmetic are the measurement problems of measuring the city, the height of the mountain, and the depth of the well, and this measurement method is called the double-difference method.
Surplus and deficiency technique: surplus deficiency technique, in the history of the development of Chinese mathematics, has a long history, is a primitive method of problem solving, (now in higher mathematics to find the approximation of the real root of the equation is developed from the ancient surplus technique), later mathematicians do not attach great importance to it, but it spread to Central Asia and Europe, before the development of European algebra, this method has been widely used to solve algebraic problems for hundreds of years, so the surplus deficit technique has a glorious position in the history of world mathematics. Jia Xian Triangle:
In his book "Detailed Explanation of the Nine Chapters of Algorithms" written by Yang Hui in 1261 AD, he recorded a diagram of the origin of the method of opening squares, which was called the Yang Hui triangle, which was a triangular array arranged with numbers. Multiplication method: that is, the numerical solution method of higher-order equations, which can obtain the coefficients of any higher-order equation.
The total number of large derivations is to solve the problem of simultaneous primary congruence groups, which has a long history in ancient Chinese mathematics, and can be traced back to the calculation of the upper Yuan year in the Han Dynasty calendar. Tian Yuan Shu:
Tian Yuan refers to the unknown number in the question, and Litian Yuan XX is equivalent to the current meaning of "let x be XX". Quaternion: It is an algebraic method used in ancient China to deal with multivariate high-level sub-range problems (up to four unknowns).
Trick Trick: that is, the interpolation method, is an important achievement of world significance in the history of Chinese mathematics Stacking technique: that is, the summation problem of higher-order difference series.
Pythagorean cone.

Anonymous users2024-02-03Both lose-lose, 360 lost a large number of users, Q lost the reputation in the hearts of many users, all in all, 360 is a slight advantage, after all, there is a mass base, QQ can force users to uninstall 360 precisely because there are already a large number of users have to use his services, 360 according to this model development, in the near future can launch instant messaging software, when the time comes, it must be Q, but this is also good, the provincial QQ monopoly, Tencent already has more than 200 softwares that can make money, and QQ is an important factor in achieving user volume. 360 take the route of free antivirus is also the same as the way QQ accumulated users before,All in all,This time it is Q injustice first,In the future,When there is a communication software even if it appears,He will lose a lot of users。 On the evening of November 3, 2010, Tencent announced that it would stop running QQ software on computers equipped with 360 software.
360 immediately launched the "webqq" client, but Tencent immediately shut down the webqq service, making the client invalid, and the incident is still developing tensely. Recently, the People's Court of Chaoyang District, Beijing Municipality has officially accepted the cases of Tencent Technology (Shenzhen) **** and Shenzhen Tencent Computer System **** (collectively referred to as "Tencent") v. Beijing Qihoo Technology****, Qizhi Software (Beijing) **** and Beijing Sanji Wireless Network Technology **** for suspected unfair competition. On the afternoon of November 10, 2010, with the active intervention of the Ministry of Industry and Information Technology and other three ministries and commissions, Tencent and 360 have been compatible.

Immediately afterwards, in the rain of bullets, a glass of beer in a plastic tube fell from the sky, spilling Atai's head and body, he was immediately angry, jumped up, and knocked down a young man in a black T-shirt to use an invincible iron fist, but unfortunately hit the wrong object, and it turned out that it was the fat man (who was a habitual offender) next to the man who threw him, and Jackson also stepped forward to help greet him, and the scene was a mess. >>>More

Those are all floating clouds The most important thing is that you play games with gift packages or something, QQ upgrades quickly, red name before the exam, online shopping discounts, feedback or something, if you don't care about these, there is no need to do a membership, it's useless.
