parabola

BITSAT 2015 Help › Co-ordinate Geometry questions › parabola

Consider a parabola Y=X²/4 and d point F(0,1).

Let A₁ (x₁,y₁), A₂ (x₂,y₂), A₃ (x₃,y₃)......,A_n (x_n,y_{_n}) are 'n' points on the parabola such x_k>0 and angle OFA_k=\frac{k\Pi }{2n} (k=1,2,3...n).Then find d value of \lim_{n\rightarrow *}\frac{1}{n}\sum_{k=1}^{n}{FA_{k}}..
here * denotes to infinite
