Cscx-cotx的导数
WebNov 17, 2016 · secx的导数为secxtanx。. 如果函数y=f(x)在开区间内每一点都可导,就称函数f(x)在区间内可导。. 这时函数y=f(x)对于区间内的每一个确定的x值,都对应着一个确定的导数值,这就构成一个新的函数,称这个函数为原来函数y=f(x)的导函数,记 … WebSolve your math problems using our free math solver with step-by-step solutions.

WebPrecalculus Examples. Rewrite csc(x) csc ( x) in terms of sines and cosines. Rewrite cot(x) cot ( x) in terms of sines and cosines. Multiply by the reciprocal of the fraction to divide by 1 sin(x) 1 sin ( x). Write sin(x) sin ( x) as a fraction with denominator 1 1. Cancel the common factor of sin(x) sin ( x). 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.
