像海伦凯勒的人还有哪些

一道关于微积分的证明题f(x)在（-∞,+∞）内有定义,对任意X1,X2,有f(X1+X2)=f(X1)+f(X2),且f(x)=1+xg(x),lim g(x)=1.证明f(x)在（-∞,+∞）内处处可导.lim g(x)=1 X趋于零时的极限，少打了，不好意思x->0 Small比较级是什么? small 的比较级 I have made a phone call with my manager and been told that he will come back today.语法都对吗 诗词原句—改写成的句子请你把这首诗的题目写下来, 改写句子（加上好词、好句,是句子更加生动,具体）1、超市的东西太多了,不一会的工夫购物车就装满了.（100字）2、公交车来了,因为等车的人太多了,我挤了半天才挤上去,而和我一道上来的 ((a^3+b^3+c^3)/3)^(1/x)当x趋近于0是的极限是x此方 abc都大于0；答案还像是abc^(1/3) (a^x-b^x)/x极限是多少,x趋近于0,如题 excited的原级、比较级、最高级的造句在今天晚上９；１０分之前给我完善的答案!
