The root of the equation f (x) = 0 is found by using the secant method. The initial guesses for the root are assumed to be x0=3 and x1=2 . Given f (3) =28 and f (2)= 4 , what is the angle the secant line makes with the x -axis?
Use the straigth line equation y = mx+b ...where m can be calculated as 24. The angle can be found using the equation for the tan.
