For f(x) = 2 functions plot the first three iterations of the Regula Falsi method starting at point a = 3, b = 3. Plot the function f() in green, the first value x1 in red, second x2 in blue and third x3 in green. You will have one plot for each function. Indicate the points x1, x2 and x3 using "scatter" function and take the size so that the points are highly visible. (as before, take 3 x 3, for trigonometric functions assume that x is in radians)
