Tan, cot, sec, and csc, calculated from trig identities. Once you know the value of sine and cosine, you can use the following trigonometric identities to obtain the values of the other four functions: Tangent is the sine-to-cosine ratio tan(α) = sin(α)/cos(α) Cosecant is the re...
初中女生爆改三角函数公式之歌 Let's sing a song about trig-functions让我们唱起三角函数的歌谣吧sin(2π+α)=sinαsin(2π+α)=sinαcos(2π+α)=cosαcos(2π+α)=cosαtan(2π+α)=tanαtan(2π+α)=tanαwhich is induction formula1, and induction formula 2这是诱导公式归类1,下面是诱导...

正弦和余弦就像好朋友:一个跟着另一个,隔开的距离是刚好 "π/2" 弧度(90°)。 正切函数 的图 正切的图有完全不同的形状……它处于正与负无穷大之间,每π弧度(180°)经过 0 一次,像这样: 在π/2 弧度(90°),和 -π/2、3π/2 等等,正切函数是未定义的,因为它可以是正无穷大或负无穷大。
