Page 2 Its like if you want to be a good pianist, you have to do a lot of scales and a lot of practice, and a lot of that is kind of boring, its work. But you need to do that before you can really be very expressive and really play beautiful music. You have to go through ...
It’s difficult to tell the difference between a macro and a variable, so we’ll use the term macro to mean something that usually doesn’t change after make starts building targets. make有许多特殊的宏和变量。很难区分宏和变量的区别,所以我们将使用术语“宏”来表示在make开始构建目标后通常不会...
ifA(x)thenB(x)’. The logic of universal conditionals is underpinned by that ofpropositional conditionals, which take the form ‘ifA(x0)thenB(x0)’, wherex0is a specific object. In mathematics, propositional conditionals are subject to amaterial conditionalinterpretation...

your Post helped me a lot! Thx! Since I needed the error ellipses for a specific purpose, I adapted your code in Mathematica. If you don’t mind, I ‘d like to share it: (*Random Data generation*) s = 2; rD = Table[RandomReal[], {i, 500}]; ...

In order not to complicate the use of symbols, when it is understood that we are talking about dynamic (over time) variables I shall write X, Y, E and D, without indicating the variable “t” as a subscript. 3. Technical note.Regarding the way to calculate the variables Xnand Yn, I...
I myself have been involved with computational thinking for nearly 40 years now—building technology for it, applying it in lots of places, studying its basic science—and trying to understand its principles. And by this point I think I have a clear view of what it takes to do computational...
In a nutshell, what happens here is that one abandons the idea of a general or unrestricted variable and replaces it with a series of variables differentiated as to type. While Cantor never laid down explicitly the principles that he was working with, it has been argued that the na¨ı...
"Well-organized and carefully written the present book is very useful to all who are interested in How Mathematicians Think!"---Ioan A. Rus, Mathematica "Byers subverts the widely held notion that mathematicians are a form of computer, or robotic followers of unbending rules. In his view, ...
