WebbFind the first approximate root of the equation 2x 3 – 2x – 5 = 0 up to 4 decimal places. Solution: Given f (x) = 2x 3 – 2x – 5 = 0 As per the algorithm, we find the value of x o, for which we have to find a and b such that f (a) < 0 and f (b) > 0 Now, f (0) = – 5 f (1) = – 5 f (2) = 7 Thus, a = 1 and b = 2 Therefore, x o = (1 + 2)/2 = 1.5 WebbLocating Roots using the Newton-Raphson Method. The Newton-Raphson method is also an iterative procedure for locating roots. To solve f ( x) = 0, Newton-Raphson uses a specific recursive formula: x n + 1 = x n − f ( x …

WebbThe roots function calculates the roots of a single-variable polynomial represented by a vector of coefficients. For example, create a vector to represent the polynomial , then calculate the roots. p = [1 -1 -6]; r = roots (p) r = 3 -2. By convention, MATLAB ® returns the roots in a column vector. The poly function converts the roots back to ... WebbThe positive root of 4 \sin x = x^2; Use Newton's Method to find the positive root of the equation \sin x = x^7 correct to ten decimal places. Use Newton's method to estimate the real solution of x^3 + 2 x - 1 = 0. start with x_0 = 0 then find x_2.
