The curve C with the equation y=exy = e^xy=ex meets the line L with equation y=exy = exy=ex at the point P.
Show that the x x\,x coordinate of P satisfies x=ln(ex)x = \ln(ex)x=ln(ex)
Use the iteration formula xn+1=ln(exn)x_{n+1} = \ln(ex_n)xn+1=ln(exn) with x0=1.5x_0 = 1.5x0=1.5 to find, to 3 decimal places, the values of x1x_1x1, x2 x_2\,x2 and x3x_3x3.
