Derive three different gx for finding roots to six correct decimal places of the following f(x)=0 by Fixed-Point Iteration. Run FPI for each g(x) and report results, convergence or divergence. Each equation f(x)=0 has three roots. Derive more g(x) if necessary until all roots are found by FPI. For each convergent run, determine the value of S from the errors ei+1/ei, and compare with S ed from calculus as in (1.11)(a) fx)23
