The value of sin −1x+sin −1x1+cos −1x+cos −1x1 is defined only when x, x1ϵ[−1,1]which is possible only when x=±1For which sin −1x+sin −1x1+cos −1x+cos −1x1=π. Calculus. Find the Derivative - d/dx cos (1/x) cos ( 1 x) cos ( 1 x) Differentiate using the chain rule, which states that d dx [f (g(x))] d d x [ f ( g ( x))] is f '(g(x))g'(x) f ′ ( g ( x)) g ′ ( x) where f (x) = cos(x) f ( x) = cos ( x) and g(x) = 1 x g ( x) = 1 x. Tap for more steps −sin( 1 x) d dx[ 1 x] - sin ( 1 x) d d x [ 1 x] Prove the following. (1) sin−1( 2x 1+x2) = 2tan−1x, |x| ≤ 1. (2) cos−1( 1−x2 1+x2)= 2tan−1x, x ≥0. (3) tan−1( 2x 1−x2) =2tan−1 x, −1 < x <1. View Solution. Q 3. If 2tan−1x = sin−1 2x 1+x2, then: View Solution. Q 4. A: The basic trigonometric functions are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). These functions relate the ratios of the sides of a right-angled triangle to the angles in the triangle. The graph of the function given by y = cos –1 x can be drawn in the same way as discussed about the graph of y = sin–1 x. The graphs of y = cos x and y = cos–1x are given in Fig 2.2 (i) and (ii). Fig 2.2 (ii) Let us now discuss cosec–1x and sec–1x as follows: Since, cosec x = 1 sin x, the domain of the cosec function is the set {x: x Vay Tiền Nhanh Chỉ Cần Cmnd Nợ Xấu.
