My apologies for my delay in posting this
latest problem. Those of you interested in knowing the reason for my

The graph of y = x2 is shown in blue on the left. When a circle is dropped into this parabola, it will be tangent to the graph at two points if its radius is large enough, as the red circle, or at one point otherwise, as the green circle. Find the radius, b, of the largest circle which is tangent to the parabola at only one point. You are visitor number 8058
