Question

hey guys, have forgotten how to do partial derivatives, can someone walk me through it plz? have 10 q's, if someone explains one i'm sure i can remember and do the rest

Answer 1

sure, ask :)

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

yes!

Answer 7

sweet, all over this puppy now!
cheers @hartnn !!
