Cscx cotx的关系
WebApr 24, 2024 · cotx的平方等于cscx的平方-1的基本公式：(cotx)^2=(cscx)^2-1。(sinx)^2+(cosx)^2=1。1+(tanx)^2=(secx)^2。1+(cotx)^2=(cscx)^2。 定义： 任意角终边上除顶点外的任一点的横坐标除以该点的非零纵坐标，角的顶点与平面直角坐标系的原点重合，而该角的始边则与正x轴重合。 WebAug 2, 2016 · Adding (1) & (2) we get. 2cscx = 2 ⇒ cscx = 1 = csc( π 2) ∴ x = π 2. Again Subtracting (2) from (1) 2cotx = 0 ⇒ cotx = 0 = cot( π 2) ∴ x = π 2. For cotx = 0 = cot(3 π 2) then x = 3 π 2 but this does not satisfy the given equation as sin(3 π 2) = −1. So only solution is x = π 2.
