We get the co-ordinates of a projectile
at t1, (a,b)
at t2 (c,d)
at t3, (e,f)
and so on as required.
Write a program in C++ to calculate equation of trajectory of projectile..

Hi PratyushTheGreat, welcome at DaniWeb!
What you need is linear regression for quadratic curve fitting (The trajecory of a projectile is parabolic.)
The link has an explanation and code in C#, but it should be fairly easy to google something in C++ I guess.

I think you will have to specify angle of projection too.
Well get the input . . . put into algorithm and then you have the output . . .provided that you know the algorithm . . .
Am too lazy to write an algorithm for you .. . so you better write your own and post it.
Good Luck.

I don't think so. It is the other way around! Once you have calculated the equation(3 points is the absolute minimum here) you could calculate that angle if you wanted to.

Dont you think with angle of projection it will be easier.
If only three points are given then that is not a problem either.
