DSolve[y'[x] + (x + 1)/x y[x] = e^x/x,y[x],x]
DSolve[{y'[x] + (x + 1)/x y[x] == e^x/x},y[x],x]
y[x] -> (E^-x C[1])/x + e^x/(x (1 + Log[e]))直接复制之后 依然无法出结果阿那个版本的Mathematics？

DSolve[{y'[x] + (x + 1)/x y[x] == e^x/x}, y[x], x]

直接得到
y[x] -> (E^-x C[1])/x + e^x/(x (1 + Log[e]))9.0 复制后显示的是 函数y的引数不存在DSolve[{y'[x] + (x + 1)/x y[x] == e^x/x}, y[x], x]

直接得到
y[x] -> (E^-x C[1])/x + e^x/(x (1 + Log[e]))
我也是9.0
