- Inverse cosine (see?)
反餘弦（看到了嗎？）
什麼是光滑函數？ (What is a smooth function?)
02:12
- Some common smooth functions are polynomials e to the x cosine of x sine of x1 over x squared plus 1.
一些常見的光滑函數有多項式、e^x、cos(x)、sin(x)、1/(x^2 + 1)。

- the time, and spin down 1/4 of the time. The probability depends on the square of the cosine
現在一個有如愛因斯坦發表的實驗可以用兩個粒子來表示，

- And so that's how it is continuous up and down and notice that there's some relationship to a sine or a And then we moved a paper past that pencil at a constant speed as this is oscillating up and down you would actually the pen would actually make that sine wave or that cosine wave as the paper is moving and as the object is oscillating up and down.
然後，我們以恆定的速度將紙張從鉛筆上移過，當鉛筆上下襬動時，鉛筆實際上會隨著紙張的移動和物體的上下襬動而產生正弦波或餘弦波。
- So there's some relationship between simplomatic motion and the sine or the cosine function.
是以，簡諧運動與正弦或餘弦函數之間存在某種關係。
