I actually write it with these little ridges in it, so SOH... CAH... TOA.

我写的时候会写成这种三角的形状，这是，，切。

This one is the tangent function, whatever that means.

这个是切函数，不管那是什么意。

So, now I'm slicing the pepper.

于是，我切着辣椒。

Hey, I'm shaving ham here, man!

伙计 我切火腿呢！

Looking at a unit circle, the tangent of any given angle is the height of this little triangle divided by its width.

观察单位，任何给定角度的切值是这个小三角形的高度除以它的宽度。

Likewise, the tangent of the second angle, theta prime, is equal to the height of the real image over the focal length of the eyepiece.

同样，第二个角的切 θ素数等于 目镜焦距上真实图像的高度。

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、、切的函数公式和转化运用对数和指数。

And I think it is to your point, like it's very sobering that sub 10% of adults now in the UK are going to reach 70, which ultimately is still you might have decades left of your life.

我认为这切中你的观点， 即现在英国只有不到10%的成年人能活到70岁， 这确实令人警醒，因为即便如此， 你的人生可能还剩下几十年。

I studied trigonometry for a month. I sometimes dreamed about sine, cosine and tangent, about mysterious angles and concussed computations, but for all this I made no real progress. I could not self-teach trigonometry. But I knew someone who had.

我学习了一个月的三角学。我有时会梦见、和切，梦见神秘的角度和让我绞尽脑汁的计算，尽管如此，我并未取得任何实质性进展。我无法自学三角学，但我认识一个自学成功的人。
