The curve integral of §10.1 to arc length
I. Introduction of the Concept
Assuming that there is a curve in the surface of the arc quality, at the beginning of the line density, and in the continuous, and the arc is the endpoint, now calculate the

The concept of §5.1 definite integral
First, from Archimedes ' exhaustion law
"Introduction" from the curve and straight line, the area of the surrounding figure.
For example: Insert a dividing point on the interval, get the point on the curve,

Flux and divergence of §10.6 Gauss formula
One, Gauss formula
The green formula expresses the relationship between the double integral on the plane closed area and the curve integral on its boundary curve, while the Gauss formula expresses the

The surface area of §10.4
I. Introduction of the Concept
1. Introduction Example
We know that if you have a thin sheet with mass density on the surface, the mass of the plane slice can be represented by the following double integral
When it is a

IntroductionIn one of my previous articles [ThoughtWorks Code Challenge--fizzbuzzwhizz Game General High Speed (C & C + +)] It was mentioned that the compiler was optimized to handle the division of the divisor as a constant, sorted out today, One

The front-end main program architecture and module division are closely linked with the division of labor and personnel, which are largely determined by the project itself. Looking at the vast majority of flash WebGame scale and difficulty, I

Calculate the maximum common divisor of two numbers by moving phase division: the code is as follows:
#includeint gcd(int a,int b){ int temp; int remainder; //if necessary,exchange a and b if(a>x>>y; fac=gcd(x,y); cout
In mathematics,Phase

The front-end main program architecture and module division are closely linked with the division of labor and personnel, which are largely determined by the project itself. Looking at the scale and difficulty of the vast majority of flash web games

This article mainly introduces the use of Int (integer) in the Python3 tutorial, the article introduced in very detailed, I believe that you learn or use Python3 can have a certain reference value, the need for friends below to see it together.
