Maths Formulas; Algebra Formulas; Trigonometry Formulas; Geometry Formulas; CALCULATORS. sin (x) = − cos(x) sin(4)(x) = sin(x). Since sin(4)(x) = sin(x), this pattern will repeat. Next we need to evaluate the function and its derivatives at 0: sin(0) = 0 sin (0) = 1 sin (0) = 0 sin (0) = −1 sin(4)(0) = 0. Again, the pattern repeats. Taylor’s formula now tells us that: sin(x) = 0 + 1x + 0x2 + 4 − 3! 1 x 3 + 0x + ··· x3 5 Solution. Verified by Toppr. The intersection point of sin (x) and cos (x) is x = π 4 between [0, π 2]. Now cos (x) is a decreasing function in the above interval while sin (x) is an increasing function in the above interval. Also. cos(x)> sin(x) between [0, π 4] while. The derivative of cos inverse is the negative of the derivative of sin inverse, given by d(cos-1 x)/dx = -1/√(1 - x 2), where -1 < x < 1 How to Find the Derivative of Cos Inverse? The derivative of cos inverse x can be determined using different methods including the first principle of differentiation, substitution method, implicit .
