PrivateSubCommand1_Click()Dima,xAsSinglea=Val(Text1.Text)Ifa再问：x=x+a*0.2+3000*0.2怎么都乘0.2呀？

把变量的取值范围贴出来.再问：求公式p=v*Z*F(s,x,y)/I。其他的一样求，其中F(s,x,y)=π/M，M=ln[2ch(πs/2y)]+ln{[shπ(x/y-s/2y)*shπ(x/y+

你给的公式不对!应该是π/2＝2^2/1*3×4^2/3*5×.×（这个公式求的精度不高!代码如下：DimPI1AsDoubleDimPI2AsDoubleDimTempAsDoubleDimnAsD

新建工程,添加command1控件.vb6.0+xp调试成功代码如下：DimnAsIntegerPrivateSubCommand1_Click()m=InputBox("请输入底数m")n=Inpu

DimsumAsInteger,iAsIntegersum=0Fori=1To100sum=sum+iNextDebug.Print"1+2+...+100=";sum

两处错误,第一个,没有赋值过程,应该改为：a=InputBox("a=")b=InputBox("b=")c=InputBox("c=")第二个：x1=(-b-d)/(2*a)应该是x2=(-b-d)

给出代码比较简单.流程图你就根据代码来画吧sum=0fori=1to10a=1forj=1toia=a*jnextjsum=sum+anextiprintsum
