Cos-1 x is neither an odd nor an even function and it falls in the range of (0,π) The maximum value of cos-1 x is π, and it lies at x = -1. The minimum value of cos-1 x is 0, and it lies at x = 1. Cos-1 x is a function that is decreasing in its domains. Cos-1 x is also a periodic function. 3. ArcTan x Double angle formulas sin(2x) = 2sinxcosx cos(2x) = (cosx)2 (sinx)2 cos(2x) = 2(cosx)2 1 cos(2x) = 1 2(sinx)2 Half angle formulas sin(1 2 x) 2 = 1 2 (1 cosx) cos(1 2 Want to see how the function cos(1/x) behaves near 0? Let's visualize this. Taylor Expansion of sin(x) example. Calculus: Integrals. example. Calculus: Integral ⇒ 2 tan-1 (2x / 1 - x 2) = π/3. ⇒ tan-1 (2x / 1 - x 2) = π/6. ⇒ 2x / 1 - x 2 = 1/√3. ⇒ x 2 + 2√3 x - 1 = 0. By comparing the above equation with ax 2 + bx + c = 0, we get. ⇒ a = 1, b = 2√3 and c = -1. By using the formula x = [-b ± √(b 2 - 4ac)] / 2a, we get. ⇒ x = 2 - √3 or - (2 + √3) But as it is given that -1 < x Find the maximum value of f(x), if f(x) = (sec^-1x)^2 + (cosec^-1x)^2 asked Nov 9, 2019 in Sets, relations and functions by SumanMandal ( 55.4k points) inverse trigonometric functions PQEPnkT.
