计算 pie 的话：

计算pie的话：

（1）Monte Carlo simulation: (x,y) where x comes from uniform [0,2], y comes from uniform [0,2]
generate (x,y) N_square times. then total up the points (x,y) where (x-1)^2 + (y-1)^2 <= 1, which is N_circle
then pie has an estimator N_circle/N_square

（2）Taylor series expansion
pie/4 = 1 - 1/3 + 1/5 - 1/7 ...   use a loop to calculate to some precision you want


（3）integral 方法咯
