- Now that you've identified all the sides relative to angle alpha do you remember the formula for finding the sine of an angle in a right triangle?
現在你已經確定了所有與角 alpha 有關的邊，還記得求直角三角形中一個角的正弦值的公式嗎？
- Yeah I know that the sine is equal to the opposite over the hypotenuse.
我知道正弦等於斜邊上的反弦。
無窮數列 (Infinite Series)
- Infinite series are also used to calculate trigonometric functions such as sine and cosine, which are very useful in determining the angles and lengths of triangles, as well as exponential functions, logarithms, and
好吧，讓我們試試一系列的術語一過n。
- Infinite series are also used to calculate trigonometric functions such as sine and cosine
無限級數也用於計算三角函數，如正弦和餘弦。
什麼是光滑函數？ (What is a smooth function?)
- 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)。
- Some common smooth functions are polynomials: e to the x, cosine of x, sine of x, 1 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)。
瑞秋·梅鐸 (Rachel Maddow) 對羅伯特·穆勒 (Robert Mueller) 去世的反應！ (Rachel Maddow reacts to Robert Mueller’s passing)
- and here was Robert Mueller, this fearsome former FBI director with this incredible sine qua non reputation.
的時刻，對公眾來說都非常重要，其中一個很有趣，
- And we open, you guys will remember, we opened up those hearings and here was Robert Mueller, this fearsome former FBI director with this incredible sine qua non reputation.
大家還記得，我們開始了那些聽證會，而 Robert Mueller，這位令人敬畏的前 FBI 局長，擁有無可比擬的聲譽。
聖母院鐘樓怪人 (Chs 1-8) - 維克多·雨果 有聲書 📚🎧 (Book 07 - The Hunchback of Notre Dame Audiobook by Victor Hugo (Chs 1-8))
- You know what servious saith: Nulus inum locus sine genio est, for there is no place that hath not its spirit." But Dom Claude, who stood in terror of some new freak on the part of Jean, reminded his worthy disciple that they had some figures on the façade to study together,
穿過這個開口的陽光，穿過了
- You know what Servius saith: 'Nullus enim locus sine genio est,--for there is no
但是 Dom Claude，他因為 Jehan 的新怪癖而感到恐懼，提醒
更廣泛的不確定性原理：關於傅立葉轉換！ (The more general uncertainty principle, regarding Fourier transforms)
- Anyway, point is, this spike you're looking at here, above the winding frequency of 5, is the Fourier transform's way of telling us that the dominant frequency of the signal is 5 beats per second, and equally importantly, the fact that it's a little spread out around that 5 is an indication that pure sine waves near 5 beats per second also correlate pretty well with the signal.
總之，重點是，你在這裡看到的高於繞組頻率 5 的尖峰，是傅立葉變換告訴我們信號的主頻是每秒 5 拍的方式，同樣重要的是，它在 5 拍附近有些分散，這表明每秒 5 拍附近的純正弦波也與信號有很好的相關性。
- And equally importantly, the fact that it's a little bit spread out around that 5 is an indication that pure sine waves near 5 beats per second also correlate pretty well with the signal.
不過大家都知道，如果是短脈衝，就意味著我們的傅立葉變換必須稍微分散一些。
