mathematical tools

: plotting tools are classified based on the nature of the generated objects. For example, you can generate different types of points in the tool box (the default icon is) and the tool box for geometric Transformation (the default icon is. The algebra window can directly enter an Algebra Expression in the geogebrar command area, and press enter, the entered Algebra Expression will appear in the algebra area, and the corresponding figure will appear in

The Fibonacci sequence is a connected sequence number, which was first invented by an Italian math. This class provides a method for calculating one or several sequence members. the use of pseudo-random numbers such as native devices, visual arts and music usually requires such control. It can also be used to check whether an integer belongs to the feberatch sequence. If you have a background in mathematics, you may have realized that PHP does not have special functions for processing advanced

Math and numerics boost. Integer This library provides a series of functions for the integer type, such as the maximum value and minimum value constant at the time of compilation [3]. The appropriate size type is given based on the required number of digits, static computing base on 2 logarithm and other functions. It also includes some Type Definitions (typedefs) of the standard header file The authors of integer are beman Dawes and daryle Walker.Boost. Interval The interval library helps

Sometimes I feel very excited about Japanese. the most impressive thing is that when I first heard of "hard work" in Japanese writing "Life is hard to handle", I was so overwhelmed. Today, I am hanging out on the Internet. I even entered a Japanese mathematics website and was surprised to find that I can understand most of the Japanese mathematical terms, and still bring a new strange feeling to people: "polygon" is called "polygon", "Trapezoid" is ca

, the "comparable number" and "the number of" can be converted into: The former is a reasonable number, the latter is unreasonable. Finally, when translated into Chinese, there is a "rational number" and "unreasonable number" of the method. We now know that the √2 discovered by Hippasos is the first irrational number born in human history. The discovery of irreducible or irrational numbers is perhaps the greatest contribution of the Pythagoras school, in the eyes of the present man. However, at

This site is a science site, often involving the input and display of mathematical formulas, which has been a problem on the web. So refer to a few online articles, and now will own the results of the study to tidy up. Main reference URL: Zhang Yang's Blog's Web math formula input and display.A Several methods of computer performance mathematical Formula 1. Desktop-facing Tex systemTex is an excellent deskt

that much. There are tens of millions of operating systems in the world. Is that all right? Of course not. However, the number of software is no longer tens of millions, right? Why? All those who have learned the dialectical materialism can draw their own inferences: "The active must be placed above the dead ". If the instruction set is not dead, there will be no compilation or linker established on the instruction set; if the compilation and the linker are not dead, there will be no operating

Note : This is a task spanning several years, and the title can also be called "learning statistics from the To Do list." When I was distressed by P-values a few years ago, I didn't know what Python was, and then, after touching Python, I liked the language. Statistics as the basis of data science, want to do this work, this is always a way around the sill.In fact, from the middle school began to study statistics, the earliest write "positive" character recount (equivalent to find the majority),

int ceil4 = (int) (Math.random()*10);sop(ceil4); This must be learned, very useful, but also very common You can also write this RandomRandom();sop(r.nextInt(10)); Most of these are the use of tools, of course, these are also more practical classes, we must master, this is a little short, because I want to open a more special knowledge class, because Java learning also quite a long time, this knowledge point we must master,

Http://sd.csdn.net/a/20120727/2807815.html Below are some posts I have seen in the Reddit Sub-Forum R/learnprogramming: "How much mathematics does a good programmer need to learn ?" "Should I study mathematics again ?" "This may be the most stupid question I have ever asked. How much mathematics does a good programmer need to learn ?" There is a misunderstanding between mathematics and programming. Many people think that mathematics must be good or have a high score before
