draw a quad bezier having curve length

[appollosputnik]

I want to draw a quad bezier curve for which I need one start point, end point and a control point. i dont have the control point but instead I have the length of the curve…Can we calculate one control point using start point, end point and curve length?… Any suggestions highly appreciated. Thanks Sujan

I don't have an answer for you but this may be of interest. It derives a closed form for the arc length of a quadratic bezier curve. Look halfway down the page.
