The roots of equation f(x)=x3−2x2−1=0, obtained after first iteration of NR method using initial guess value x0=1 is
While finding the roots of f(x)=x2−4=0 using Newton - Raphson method, initial value of (x, x1 = 1). If the value obtained after first iteration is x2, find [100. x2], where [ ] is the greatest integer function.
