the direction of the gradient is the direction of greatest increase

rsvitale Group TitleBest ResponseYou've already chosen the best response.2
so take (dF/dx,dF/dy) at the point (1,1) and that vector points in the direction of greatest increase

rsvitale Group TitleBest ResponseYou've already chosen the best response.2
the magnitude of that vector is the greatest rate of change

those look good for the gradient stuff

yep they are right, now evaluate the derivatives at the specified point and you have the gradient vector. Then you can find magnitude.

so eval at (1,1) fx=1 fy =1

magnitude is \sqrt((a_1)^2 + (a_2)^2) so I use the 1,1 ?

dabears900 Group TitleBest ResponseYou've already chosen the best response.0
so the magnitdue is sqrt(2) ?
