As I said, n is just some constant in that particular equation. And I am saying that equation works, when f(0)=0, and indeed you can try it.
Of course you can find f from its derivatives... its called an integral, and I am not searching for the integral, but looking to approximate its value at...
I have tried searching and have not come up with an answer to this question - but have come close in my own work (i think). Note: I want to solve this numerically, or by some formula.
I am trying to solve this problem, save I have function f(x), the equation is not known. Its derivative...
