Chapter 5, Problem 6P

Determine the positive real root of $\ln \left(x^2\right)=0.7$(a) graphically, (b) using three iterations of the bisection method, with initial guesses of $x_l=0.5\text{ and }{x}_u=2$, and (c) using iterations of the false-position method, with the same initial guesses as in (b).
