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

我写时候会写成这种三形状，这是正弦，余弦，正切。

Hey, I'm shaving ham here, man!

伙计 我正切火腿呢！

He went to a seat of learning, took a seat, and prepared to learn some secant on math.

他去了术中心，坐下，准备些数正切。

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

察一个单位圆，任何度正切都是这个小三形高度除以它宽度。

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，第二个正切 θ素数等于 目镜焦距真实图像高度。

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

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.

我习了一个月三。我有时会梦见正弦、余弦和正切，梦见神秘度和让我绞尽脑汁计算，尽管如此，我并未取得任何实质性进展。我无法自三，但我认识一个自成功人。
