take the sum of squares and differentiate wrt A and B.

Impressive, we got you to do some decent work. The normal equations look good, but you left out the sums in the partial derivatives in the previous set of equations.
a few adjustments.... Originally Posted by zorro Differentiating wrt to A and B we get and the normal equations are
