The main technique that's been used for hundreds of years is maths, or trigonometry, to be precise.

数学，或者更准确地说，三角学，是已经使用了数百年的主要技术。

And if brains salt code just as math, we could teach it like we teach algebra or trigonometry.

如果大脑把编码当作数学，我们就可以像教代数或三角函数一样教它。

Today we did, um... trigonometry, which we have never covered before and we did it in, like, 15 minutes.

今天我们学了。以前从未学过的三角函数，他花了十五分钟就讲完了。

And the answer will involve some trigonometry.

答案将涉及一些三角学。

Let me write soh cah toa at the top because this is really just trigonometry.

让我在顶部写上 soh cah toa 因为这实际上只是三角函数。

It's all just trigonometry, connecting sides and angles through sines and cosines.

这是三角学，上边 以及跨正弦和余弦的角度。
