改进的牛顿法求解：

方程的构造方法:给出[0,1]区间上的随机数(服从均匀分布)作为方程的根p*.

设你的班级数为a3,学号的后两位数分别为a2与a1,从而得到你的三次方程



例如:你的31班的12号,则你的方程是21x3+60x2+2x+a0=0的形式.

方程中的系数a0由你得到的根p*来确定.

-improve Newton's method : Construction of the equation : given interval [0,1] on the random number (subject to uniform distribution) as the root equation p*. set up your classes at a3, after learning of the double-digit for a1 and a2, so you get the three equations for example : Your 31 classes on the 12th, then your equation is 21x3 60x2 2x a0 = 0 forms. the equation coefficients a0 you get from the root of p* to determine.
