You put your horizontal " X" coordinate here, vertical " Y" coordinate here.

你把横坐标" X" 值输在这里纵坐标" Y" 值输入这里。

To begin with, we can input our values with  reasonable certainty.

首先，可合理确定地输入的值。

Behind the scenes, this operating system uses buffers for storing the text values that are entered.

幕后，这个操作系统使用缓冲区输入的文本值。

But it wasn't too restrictive -- you could still put any value, any formula, in any cell.

但它并没有太多限制——您仍然可在任何单元格中输入任何值、任何公式。

They look something like this: Now, let's put in some real values.

它看起像这样：现在，输入一些实际的值。

We can write out a little logic table that shows the original value under Input, and the outcome after applying the operation under Output.

可写出一个小逻辑表，表中输入栏显示原始值，输出栏显示应用操作后的结果。

If you go an plug these into a calculator, you'll notice that the arctan of each such small value is quite close to the value itself.

如果你把这些值输入计算器，你会注意到每个这样的小值的反正切值非常接近该值本身。

That is the basis of digital computing. Those operations compared to input values and spit out a third as a result some such as and or not.

那是数字计算的基础。这些操作会比较输入值，并输出第三个值作为结果，比如与、或、非等运算。

So it takes some time for the input values to travel through all these things to the output value until the signal is stable on the output.

因此，输入值需要一些时间才能通过所有这些东西到达输出值，直到信号在输出端稳定为止。

And then suppose I say, I'll just tell you what the outputs of this polynomial would be if you inputted various different inputs like 0, 1, 2, 3 on and on.

然后假设说，会告诉你这个多项式在输入不同的值比如0, 1, 2, 3等等时的输出结果。

I think that's because if you put something like age into your statistical analysis program, your computer will spit out values, like the average age or the average BMI, to several decimal places.

认为这是因为如果你在统计分析程序中输入年龄之类的值，你的计算机会吐出平均年龄或平均 BMI 等值，精确到小数点后几位。
