Thanks for your help HallsofIvy. I'm not a mathematician, so I find it quite difficult, please understand. The expression you worked out is for my 2nd case right? (I guess you just did a couple of typos, but that's why I'm not sure). With your example I think I should be able to work out...

I would break them into two separate derivatives (f'^2)' and same for g then 2f' but I wonder what happens with a different axis such as (Fy^2)x even worse with the products (the second case) unfortunately I don't have much theoretical knowledge on partial differentiation (it's been...

Homework Statement Given two functions F and G, I will use the following notation to indicate partial differentiation: Fx means dF/dx Gz means dG/dz (for example) I would like to develop the following two expressions. I don't want them grouped into brackets as they're now, but I have...
