3. 余割函数（cosecant function）：余割函数是正弦函数的倒数，表示一个角的余割值。在数学中，余割函数通常用 csc(x) 表示。4. 三角恒等式（trigonometric identity）：三角函数之间存在许多重要的恒等式。其中一个是 tan^2(x) + 1 = sec^2(x)。这个恒等式表明，正切函数的平方加上1等于余割函...
数学中tan是正切的意思。角θ在任意直角三角形中，与θ相对应的对边与邻边的比值叫做角θ的正切值。若将θ放在直角坐标系中即tanθ=y/x。tanA=对边/邻边。在直角坐标系中相当于直线的斜率k。
根据这些定义，可得到下列恒等式（identity）：tanθ＝sinθ/cosθ，cotθ＝cosθ/sinθ secθ＝1/cosθ，cscθ＝1/sinθ 分别用cos 2θ与sin 2θ来除cos 2θ＋sin 2θ＝1，可得：sec 2θ–tan 2θ＝1 及 csc 2θ–cot 2θ＝1 对于负角度，六个三角函数分别为：sin(–θ)＝ –sin...
