WebIf cos −1x>sin −1x, then x belongs to the interval A [−∞,0] B [−1,0] C [0, 21] D [−1, 21] Medium Solution Verified by Toppr Correct option is D) Given, cos −1(x)>sin −1(x) cos −1(x)> 2π−cos −1(x) ....... [∵sin −1x+cos −1x= 2π] 2cos −1(x)> 2π cos −1(x)> 4π x WebWe calculate sin of sin inverse of x using its definition mentioned in the previous section. So to calculate sin (sin -1 x), See whether x lies in the interval [-1, 1]. If so, sin (sin -1 x) = x. …
If sin-1x+ cos-1(1-x)= sin-1(-x) , then x satisfies the equation
WebIf sin−1 x+ cos−1(1 − x) = sin−1(−x) , then x satisfies the equation 2862 63 Inverse Trigonometric Functions Report Error A 2x2 −x +2 = 0 B 2x2 −3x = 0 C 2x2 +x −1 = 0 D none of these Solution: sin−1x +cos−1(1−x) = sin−1 (−x) ⇒ cos−1 (1− x) = −sin−1 (x)+ sin−1(−x) ⇒ cos−1 (1− x) = −2sin−1x ⇒ 1−x = cos(−2sin−1x) Web11 sep. 2014 · f '(x) = 1 √1 −x2 as one of derivative formulas; however, you can derive it by implicit differentiation. Let us derive the derivative. Let y = sin−1x. By rewriting in terms of sine, siny = x By implicitly differentiating with respect to x, cosy ⋅ dy dx = 1 By dividing by cosy, dy dx = 1 cosy By cosy = √1 − sin2y, dy dx = 1 √1 − sin2y By siny = x, nutcracker ballet in los angeles

If 3 tan − 1 x + cot − 1 x = π, then x equals : … WebIf Y = (Sin−1 X)2, Then (1 − X2)Y2 is Equal to (A) Xy1 + 2 (B) Xy1 − 2 (C) −Xy1+2 (D) None of Theseb - Mathematics Shaalaa.com Department of Pre-University Education, Karnataka PUC Karnataka Science Class 12 Textbook Solutions 13651 MCQ Online Mock Tests 17 Important Solutions 994 Question Bank Solutions 10088 Concept Notes & Videos 386 … Websin -1 (sin x) = x, only if x is in the interval [-π/2, π/2]. If x is NOT in the interval, then find two multiples of π such that x lies between them. Then find "odd multiple of π - x" and "x - even multiple of π". Choose one of these angles which lies in [-π/2, π/2] to be the value of sin -1 (sin x). What is Sin of Inverse Cos x? non-christian names
