SUMMARY
The discussion focuses on applying the chain rule to compute the second derivative of multivariable functions, specifically for the function F(x,y) where y=y(t) and x=x(t). The correct formulation for the second derivative, Ftt, is established as Ftt = (Fxx*xt + Fxy*yt)*xt + Fx*xtt + (Fyx*xt + Fyy*yt)*yt + Fy*ytt. Participants confirm the necessity of including mixed partial derivatives F_xy and F_yx in the calculations, emphasizing the use of both the product rule and chain rule in this context.
