1. Compute a sequence of ratios, AY AX for the function y = x with respect to the fixed point P = (20, 400). Use AXn = -, n = 1, 2, 3,. .to generate a sequence of points On = (20 + 2), (20 + 2)") and so a sequence of ratios Ayn (20 + 2 ) - ( 20 ) 2 Show that as n - co (i.e., Xn - 0) this ratio Ayn Axn (20+2) -(20) Axn converges. Using this result find the tangent line to the function y = x2 through the point P = (20, 400)
