Cscx-cotx的导数
Did you know?
WebSimplify (csc(x))/(cot(x)) Step 1. Rewrite in terms of sines and cosines. Step 2. Rewrite in terms of sines and cosines. Step 3. Multiply by the reciprocal of the fraction to divide by . … 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.

Web图4 y=sinx和y=cscx. 这里我强调一个点,就是周期性. 由图3和图4可知,正割函数和余割函数都是以2pi为最小正周期的. 但我们知道,正切函数的最小正周期是pi. 所以若根据tan与cot互为倒数来演变画图像,我们可以知道y=cotx的最小正周期也为pi Web6 人 赞同了该回答. 记忆原理,而非结论。. 你直接背,不仅难,而且还容易记混;搞懂了原理,随手就可以计算。. 关于三角函数(不含反三角函数),实际上只 有两个核心导数公式 :. (sinx)'=cosx. (cosx)'=-sinx. 其 …
