Cscx cotx的关系
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.
