Solve 2-7x+6=0. (a) Write the scheme of the Secant method for solving this equation and then apply it to find p3 with po = -0.5 and p = -1.5 by hand calculation. (Do not use code). (b) Use the secant method to find the solution accurate to within 10-6 for -7x+6=0 on [-2,0] by code with po = -0.5 and p = -1.5. (Use code "alg024Secant.m".) Does the secant method need more iterations comparing to the usual number of iterations" for the Newton's method?
