以flash 實做三角函數觀查角度與徑度的變化

$\sin x = \frac {a}{c}$

$\cos x = \frac {b}{c}$

$\tan x = \frac {a}{b}$

${rad}=\pi{\frac{deg}{180^{\circ}}}$

常用的弧度轉換公式：

$2\pi \leftrightarrow 360^{\circ}$

$\pi \leftrightarrow 180^{\circ}$

$\frac{\pi}{2} \leftrightarrow 90^{\circ}$

$\frac{\pi}{3} \leftrightarrow 60^{\circ}$

$\frac{\pi}{4} \leftrightarrow 45^{\circ}$

$\frac{\pi}{6} \leftrightarrow 30^{\circ}$

HTC Desire 的雙向錄音功能的點殘缺

用一陣子，才想到要錄音的功能，所以在Market 找了兩三套來試，都有想同的問題，就是另一方通話的聲音太小了，在想不會那麼巧吧!，所以在網站爬了一下。原來問題在 Android 不知道Google 什麼會改善。
