有关计算方的经典算法的C程序，迭代、插值、各类积分公式，常微分方程的数值求解、Gauss列主元消去法-side of the calculation of the classical algorithm C procedures, iterative, interpolation, all integral formula, and often the numerical solution of differential equations. Gauss out PCA elimination

实现微积分函数，当横坐标X逐步增大时，纵坐标实时显示Sin，Cosn函数的数值，并同时分别显示两者的微分、积分函数值，并同时在显示区域显示出来，完全自己用两天时间写出来教入门选手的。-Calculus to achieve function, when the abscissa X gradually increases, the longitudinal coordinates of real-time display Sin, Cosn function value, and at the
