xy=x+y x =2 2x2=2+2 xyz=x+y+z x=1 if y=2 if z=3 1x2x3=1+2+3 or 6=6 unless x y z all equal 0

I see many correct answers already, so I'll divert here. delta=>change, so the change in the function with respect to the change in X is asking,,, if I locked the Y-input for a while and just moved the input for X the tiniest amount possible, how fast would the function change as a whole? To know that change anywhere on the X-axis, put in the X-value to Y^2+2XY
You basically do normal derivatives on the function but you pretend the symbols not shown in the delta denominator are constants; eg treat them like they were a number, say 13 or -4.59812382.

What the deal with this question. Ive seen it three times and its not even that hard, yet three people i guess from the same class cannot answer it..
Δƒ/Δx = y² + 2xy
Δƒ/Δy = 2xy + x²

Δƒ/Δx = y² + 2xy
Δƒ/Δy = 2xy + x²
( i assume you want to know the partial derivatives )

Df/Dx is the derivative of f for x so just derive x while considering y constant:
Df/Dx = y^2 + 2xy
and Df/Dy = 2xy + x^2

This is really bothering me now.
): <
edit:
This question was posted over and over by different people last night, someone said it's because they were trying to win an iPod. That's really lame.
If you really want to know how to do it, here let me explain it to you.
To find the partial derivatives of f:
For the first one, df/dx, you will have to differentiate with respect to x, this means to treate y as a constant.
For the second one, df/dy, differentiate with respect to y instead, this time you treate x as a constant.
now get the answer yourself ^-^

thats all the problem consits of? theres no more information? that looks like too many variables with no given numbers but thats just me.
