boundary judgment is for a picture of a square. First, the original image relative to its own four coordinates mapped to the matrix corresponding to the screen point coordinates. By getting the coordinates of the 4 points, we can correlate the coordinates of the picture with the 4 point coordinates of the picture according to the finger's touch. The logic of the boundary judgment is that the finger touches the picture by the distance of the point to 4 vertices and if the length of the

C language cos () function: Cosine valueheader file: #include The Cos () function is used to find the cosine value, that is, the ratio of the side length of the angle to the length of the hypotenuse, and the prototype is: Double cos (double x); The "parameter" x is a radian. Return value returns the calculated result from 1 through 1. The relationship between radians and angles is:radians = 180/π angleAngle =π/180 radian

Time Limit: 2 seconds memory limit: 65536 KB Mathematics can be so easy when you have a computer. consider the following example. you probably know that in a right-angled triangle, the length of the three sides a, B, c (where c is the longest side, called the hypotenuse) satisfy the relation A * A + B * B = C * C. this is called pythagora's law. Here we consider the problem of computing the length of the third side, if two are given. Input The input

The definition of C functions is divided into two parts: function declaration and function body. 12. If you want to call C functions and put them under the main function, you must declare them on the main function before running the function, then you can only put the function on the main function. 13. function value passing is di
