You know, cosine is adjacent over hypotenuse.

你们知道 cos除以斜。

So you have the opposite over the hypotenuse.

里对比斜。

I get it! Sin is opposite hypotenuse... Yes.

我懂了，正弦对比斜。的。

So this is equal to cosine of the angle.

cosθ等于/斜。

Opposite over hypotenuse is equal to sine of an angle.

斜分之对 的值即 sin 函数的值。

And so this is going to be equal to what?

相对于个角 里/斜？

What involves the hypotenuse and the opposite side?

什么涉及斜和对？

You know, I was blown away that the square of the hypotenuse was the sum of the squares of the opposite sides.

斜平方等于直角平方和可把我给惊呆了。

So what involves the opposite and the hypotenuse?
