Question from ABHILASH.: Sir, |
Abhilash,
This involves finding the arc length of a parabola. If the parabola is y = x2/(2p) then the arc length expression requires you to integrate sqrt[1 + x2/p2]. The value of this integral can be found at http://home.att.net/~numericana/answer/calculus.htm#parabola or by using The Integrator. If you use The Integrator you need to know the correct notation in Mathematica. The expression to integrate is Sqrt[1 + x^2/(p^2)].
