Course: Numerical Methods for engineers

Ch1 or 2

For the following function f(x) = 4x3 - 6x2 + 7x - 2.3: 1-Use MATLAB to graph the function f(x) for x=0:0.1:3. From the graph, find the root value Xr at f(x)=0. Provide graph and Matlab script file. 2- Determine the real root of the function using the following iterative numerical methods: a) Bisection method initial values Xu=0.2, Xu=2) b) False position method with two initial points X_=0.2, X.=2; c) Newton's method (initial value Xo=0.2) d) Secant Method (initial value X:-1=1.5. Xi=2) Notice: use relative persent approximate error Ea with stoping criterian error with specified erro Es=1%
