PrivateSubCommand1_Click()DimsumAsDoubleDimiAsLongDimnAsDoublen=((1/(10^-5))+1)/2'正好等于10^-5时候n的值
公式:π/4=1-1/3+1/5-1/7+...求值n=0sn=0an=1dountilABS(an)
1、循环前面加一条:pi=02、i=-1改为i=-1*i

应该是Pi/4=1-1/3+1/5-1/7+…+(-1)^(n-1)/(2*n-1)吧,PrivateSubForm_Load()DimPiAsSingle,iAsLongForm1.AutoRedr
#include<stdio.h>main(){ longi,a=1,b=3; doublep=1,t=1,t1=0; while(t-t1>=1e-8
返回一个包含随机数值的Single.语法Rnd[(number)]可选的number参数是Single或任何有效的数值表达式.返回值如果number的值是Rnd生成小于0每次都使用number作为随机
原文6题:ACDCCC补充6题:DABDCA
DimpiAsDoubleDimSAsDoubleDimiAsDoubleDimViAsDoublei=0S=0DoWhileTrueVi=1/(2*i+1)'第i项的值:1,1/3,1/5,1/7.
我帮你改了一下,你看看把再问:答案是接近3.14么、图上看不出来、貌似是3.19吗?能把程序复制发来么、我运行一下,多谢
