The enhanced Fujita scale rates tornadoes based on how much damage they cause.

增强藤田按照龙卷风造成伤害规模分。

Anything above 200 miles per hour is considered an EF-5 tornado.

只要超过每小时200英里速度都会被认为是藤田5龙卷风。

Fujita is the namesake of the enhanced Fujita Scale which characterizes the intensity of tornadoes.

改进版藤田是以藤田命名，该述了龙卷风强度。

Does Newton's infinite series actually give you the value of one over one plus X?

牛顿无穷实际上给出是一除以一加上 X 值吗？

So that just alternating series with plus and minus signs as the coefficient.

因此这只是以正负号交替作为系。

So to summarise, trophic levels are the number of steps in an organisms is within a food chain.

总，营养是一个生物体在食物链中层。

So, now, the EF scale, Enhanced Fujita Scale, starts at 0 and goes only to 5.

现在, EF, 增强藤田，从0开始, 只到5。

Its wind speeds were greater than 200 miles per hour making it an EF-5 tornado, the strongest classification on the Enhanced Fujita Scale.

龙卷风风速每小时超过200英里，为EF-5型龙卷风，是改良藤田最高强度。

More generally, this is the core idea  that underlies Fourier transforms, and Fourier series, and the infinite  swell of topics that follow from those.

更一般地说， 这是傅里叶变换和傅里叶核心思想，以及随来无穷无尽主题。

To be more precise about it, the Taylor series expansion of tan(theta) shows that this approximation will only have a cubic error term.

更准确地说，tan(theta) 泰勒展开表明该近似值仅具有三次误差项。

We can find out where that point is by writing the infinite series that represents each strategy, setting them equal to each other, and solving for delta.

我们可以通过写出代表每个策略无限，将它们设置为彼此相等，并求解 delta 来找出那个点在哪里。

A number one bigger than this was in the series expansion of a fundamental function in a totally different part of math, relevant to these things called modular forms and elliptic functions.

比这更大一个是学中完全不同部分基本函展开，与模形式和椭圆函相关。

If you put in minus a quarter for X in this series, you'll get a very rapidly converging series expansion that will quickly give you square root of three to high accuracy.

如果你在这个系列中为X减去四分一，您将得到一个非常快速收敛展开式，它将快速为您提供高精度三平方根。

Whereas most of these developments were driven by a company's need to develop their own system to count their proceeds or a mathematical progression that necessitated a new tool–a more powerful tool–in this case, TI had invented the microchip.

虽然这些发展大部分是由公司需要开发自己系统来计算其收益或需要新工具（一种更强大工具）学推动，但在这种情况下，TI 发明了微芯片。
