I asked you to give A. You failed; you gave an answer for C, not A.

Now lets see what you answer is.

Recap the problem: r = sqr(At^2 + Bt + C)
Then YOU wanted to include c1=r(0), c2=r'(0) and c3=r"(0)

Ok...

r(0) = sqr(A*0^2+B*0 + C) = sqr(C). Thus
c1 = sqr(C) thus C = c1^2. This is much different from your answer of

> C=c_1*c_3^2-c_2/c_1

You failed again.

Its useless to teach you math and physics. You need to start over at
the kindergarten level, something we dont do here in this NG.
