Use the secant method on the circle function (x + 1)2 + (y – 2)2 = 16 to find a positive real root. Set your initial guess to xi = 3 and xi-1 = 0.5. Approach the solution from the first and fourth quadrants. When solving for ƒ(x) in the fourth quadrants, be sure to take the negative value of the square root. Why does your solution diverge?
