But let me go back to these sines, cosines and logarithms.

但让我们再来说说正弦、余弦和对数函数。

And that motion is mathematically identical to the motion of something bouncing up and down on a spring with a linear restoring force - also sine waves over time.

这种运动在数学上和一个物体在弹簧上以线性恢复（随化的正弦波）上下弹跳的运动是一样的。

I'm just about working with our natural ebb and flow of energy and working with our natural ebb and flow of interest almost like a sine wave.

我只是说要顺其自然，顺从我们兴趣的波澜，就像正弦波一样。

It found favour, and in particular it accelerated the completion of a genome-sequencing project for the animals-a sine qua non for any self-respecting model organism.

这一想法得到了青睐，尤其是会加速动物基因组测序项目的完成，这是任靠谱的模式生物的必要条件。

Over the course of a year, the amount of daylight you experience on a given day oscillates in what's basically a sine wave.

在一年中，你在某一天经历的日照基本上是一个正弦波的振荡。

The force required to lift is reduced by the sine of the angle of the stairs, call it 30 degrees, so, about half.

运上去所需的度按梯角的正弦值减少，30度角的话就减少一半。

So for the sine qua non of the human mind, DeepMind was non compos mentis and out of its depth.

因此，对于人类思维这个必要条件来说，DeepMind 既无判断能，也不从心。

So we generate this swept sine wave and we use that to capture the acoustic of the cave.

我们生成这个正弦扫频信号，然后利用它来测定洞穴的声音特性。

We draw them as sine waves, as if something's going back and forth or up and down.

我们把它们画成正弦波，就好像有东西在前后或上下运动。

But that sine wave is just gonna be a tremendous load on all the health care providers.

但这个正弦波对所有医务工作者来说都是巨大的工作量。

What's the sine of 30 degrees?

sin30度等於多少？

This seapower approach to the world became the sine qua non of early American foreign policy.

这种对世界的海权方针成为早期美国外交政策的必要条件。

So, for example, I don't think that being a math person means that you can recite the formulas between the sines, cosines, tangents and to use logarithms and exponentials interchangeably.

所以，比如，我认为成为数学家不是指你要能背诵正弦、余弦、正切的函数公式和转化运用对数和指数。

He'd watch the broken sine wave of the telephone lines, looping on and on and on for miles, then veering away, then rejoining the bus's path.

他会观察电话线发出的断断续续的正弦波，起起伏伏，绵延数英里，转向别处，然后又重回公交车的路线上。

So what's the sine of 30?

sin30°是多少？ 实际上 我们写到这里？

This should start to become a little second nature to you that this is T1 sine of 30, this y component right here.

这应该对你来说很自然这是T1sin30° 这个y分量。

These are the plaintiffs, Valerie and Anthony Sines.

他们是原告，瓦莱丽与安东尼·锡尼什。
