complex numbers

基本解釋

There is a brief discussion of two dimensional mechanics in terms of complex numbers.
這里有關于用復數(shù)來講二維力學的簡短討論。
Keeping in mind that complex numbers are incomparable even to each other, while Unicode objects only have problems comparing to some strings, we can use
請記住，即便是復數(shù)與復數(shù)之間也不能進行比較，而 Unicode 對象只在與某些字符串比較時會出問題。
Mathematicians are familiar with this; common problems in algebra are more tractable when considered over the complex numbers than over the reals, even though complex arithmetic is more difficult.
數(shù)學家對此很熟悉；如果將代數(shù)中的常見問題考慮成復數(shù)而不是實數(shù)時，那么這些問題就更容易處理，盡管復數(shù)算法較難。

I think that book will give you all the basic principles you need in calculus of one variable, more variables, elementary complex numbers, maybe solving some problems with vectors and so on, which you're going to get into.
我想那本書會給你所需的所有基本知識,包括一元和多元微積分,簡單的復數(shù)運算,可以解決一些與矢量有關的問題,而這正是你們將要學的

Complex numbers, which have a real and an imaginary part added together, are the points on this plane that do not lie on either axis.
