Example 1: Find the first approximate root of the equation 2x3– 2x – 5 = 0 up to 4 decimal places. Solution: Given f(x) = 2x3– 2x – 5 = 0 As per the algorithm, we find the value of xo, 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, xo= (1 … See more Suppose we have an equation f(x) = 0, for which we have to find the solution.

WebExample: The function g ( x) = 2 x ( 1 − x) violates the hypothesis of the theorem because it is continuous everywhere ( − ∞, ∞). Indeed, g (x) clearly does not map the interval [ 0.5, … WebJun 8, 2024 · It seems that this function could not use Fixed Point Iteration to solve, since f (x)=0 equals to g (x)=x and g (x)= (x+1)^ (1/3)+x here. But if we plot g (x) (blue curve) with h (x)=x (red curve), we have: So if we start at 0, the iteration can't convergence ( x1 will increase dramatically but the root is -1 ). Hope it helps!
