问题描述：
高数 真诚求学 微积分 求左边的黎曼和 急
2^(1/2)/10*((sin(4/2)+sin((4+0.05)/2)+sin((4+0.05*2)/2)+sin((4+0.05*3)/2)+sin((4+0.05*4)/2)+sin((4+0.05*5)/2)+sin((4+0.05*6)/2)+sin((4+0.05*7)/2)+sin((4+0.05*8)/2)+sin((4+0.05*9)/2)+sin((4+0.05*10)/2)+sin((4+0.05*11)/2)+sin((4+0.05*12)/2)+sin((4+0.05*13)/2)+sin((4+0.05*14)/2)+sin((4+0.05*15)/2)+sin((4+0.05*16)/2)+sin((4+0.05*17)/2)+sin((4+0.05*18)/2)+sin((4+0.05*19)/2)))
我上面的式子有什么问题吗?错在哪里 为什么显示错误?
