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

但让我们再来说说正、余和函。

Opposite over hypotenuse is equal to sine of an angle.

斜边分之边 的值即是 sin 函的值。

So what's the sine of 30?

sin30°是多少？ 实际上 我们写到这里？

This is equal to the sine of theta.

两侧以同时乘以重力的大小。

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

这种世的海权方针成为早期美国外交政策的必要条件。

So this is going to be equal to the sine of theta.

两侧以同时乘以重力的大小。

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，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.

但这个正所有医务工作者来说都是巨大的工作量。

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

我们生成这个正扫频信号，然后利用它来测定洞穴的声音特性。

I'm gonna use sine of theta, oh sorry, sine of phi.

我要使用正 theta， 哦抱歉，正 phi。

So each of the x sine in the sample.

所以样本中的每个 x 正。

The man was tired of teaching sine for students.

这人厌倦了为学生教授正。

And now for the Y direction we can use the definition of sine of theta.

现在于 Y 方向，我们以使用正函的定义。

For sine, they add to zero.

于正，它们加到零。

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

这应该你来说很自然这是T1sin30° 这个y分量。

I don't have the slightest idea what sine and cosine mean.

我根本不知道正和余是什么意思。
