• 有关考研高数的问题已知分段函数f '(x)=1,x属于－∞到0；f '(x)=e^(x/2),x属于0到+∞,f（0）=0,求f（x）的表达式.答案是这么做的：因为f '(x)=1,所以f（x）=x+c,c=0；因为f '(x)=e^(x/2),所以f（x）=2e^(x/2)+c,c=-2.综上,f（x）=x,x∈（－∞到0】；f（x）=2e^(x/2)-2,x∈（0到+∞）.我是这么想的：f（x）在－∞到+∞上,=∫（0到x）f '(t)dt.当xx∈（－∞到0】时,f（x）=∫（0到x）dt=x；当x∈（0到+∞）时,f（x）=∫（0到x）e^(t/2)dt=2e^(x/2)-2,我感觉这么做好像不对,只是巧了才跟答案一样,但是不知道为什么不对,这道题是不是不能用变上限积分的知识来做,
