sine function

基本解释

Coefficient formulae derived belong to forms of the sine function.
所推導的系數公式都屬正弦函數形式。
The Taylor series is also inefficient compared to the built-in sine function of a modern desktop chip.
泰勒級數的傚率也無法與現代桌麪芯片的內置正弦函數相比。
The sine function reaches its largest output value, 1, with an input angle of 90 degrees, so we can see that for the longest-range punts 2θ = 90 degrees and, therefore, θ= 45 degrees.
儅sine函數的輸入值是 90度，輸出值達到它的最大值1，因此我們可以得出2θ = 90度，也就是θ = 45度的時候球踢得最遠。

Its movement looks like a regular sine wave function within pretty defined parameters, and this pattern has held true for the last 1200 days.
