//下面是画圆的程序， //画线、画圆、画各种曲线其实都很简单，归根到底就是x、y的二元方程嘛 //对算法感兴趣的话建议去找本《计算机图形学》看看，不是卖关子哦。实在是几句话说不清除，呵呵 // ---------------------------------------------- //字节 void circleDot(unsigned char x,unsigned char y,char xx,char yy)//内部函数，对称法画圆的8个镜像

用梯形法求二次曲线定积分的C++源代码：只要设定二次曲线方程的系数、积分区间和等分数，就可自动获得积分值。-Trapezoidal method and the quadratic curve C source code for the definite integral: as long as the set of the quadratic equation of the Department ofNumber of the integration interval and scores,
