内容简介

　　Calculus of real-valued functions of several real variables， also known as multivariable calculus， is a rich and fascinating subject. On the one hand， it seeks to extend eminently useful and immensely successful notions in one-variable calculus such as limit， continLuty， derivative， and integral to "higher dimensions." On the other hand， the fact that there is much more room to move about in the 'n space Rn than on the real line R brings to the fore deeper geometric and topological notions that play a significant role in the study of functions of two or more variables.

我为什么喜欢在京东买东西，因为今天买明天就可以送到。我为什么每个商品的评价都一样，因为在京东买的东西太多太多了，导致积累了很多未评价的订单，所以我统一用段话作为评价内容。京东购物这么久，有买到很好的产品，也有买到比较坑的产品，如果我用这段话来评价，说明这款产品没问题，至少85分以上，而比较垃圾的产品，我绝对不会偷懒到复制粘贴评价，我绝对会用心的差评，这样其他消费者在购买的时候会作为参考，会影响该商品销量，而商家也会因此改进商品质量。
