Numerical methods of finding roots examples
Web20 feb. 2016 · What I have done so far: I attempted to use a numerical method, more specifically the secant method to find the roots (x=1,2,3) of the function f (x)=x^3 … WebFor a better understanding of the method let us consider one more example. Example 1 : Find the approximate value of the real root of the equation Solution : Let f(x) = 2x - 3 sin x - 5. t Since f(-x) = -2x + 3 sin x - 5 < 0 for x > 0, the functian f(x) is negative for all negative real numbers x. Therefore the function has no negative real root.
