To simplify the given function of trigonometry, we will apply the trigonometry identities. Following is some important trigonometry identities: 2sin(x)cos(x)=sin(2x)cos2(x)−sin2(x)=cos(2x)1+cos(2x)=2cos2(x)1−cos(2x)=2sin2(x) ...
Sin 函式傳回引數 (以弧度為單位的指定角度) 的正弦值。Tan 函式傳回引數 (以弧度為單位的指定角度) 的正切值。反函式Acos 函式傳回其引數的反餘弦值。 反餘弦值是以其餘弦值為引數的角度。 傳回的角度會以弧度為單位,範圍從 0 (零) 到π。
