Question

hartnn · Answer

sure, ask :)

jack1 · Answer

f(x,y)=y^3x^2
calculate df/dx (x,y)?
cheers @hartnn  ;)

hartnn · Answer

so you are calculating the derivative w.r.t 'x' 
treat 'y' as constant

hartnn · Answer

its like differentiating a^3x^2 or just cx^2

jack1 · Answer

ahh, gotcha, so f(x,y)=y^3x^2 = (k) x^2
so f'(x,y) wrt x = 2k x? 
                          = 2 (y^3) x??

hartnn · Answer

yes!

sweet, all over this puppy now!
