Just pull the trigger and fire the slug through my brain so that I may be enlightened in my moment of death as to what the answer to this 'mickey mouse' question is.

I don't think you understand what a differential is.

It's 0, isn't it? Since xx is treated as a constant.

Just tell me the answer you patronising piece of cabbage!

Well, it's just the rate of change of x with respect to y...
Let me break it down for you eggheads,

s=xs=x. I am trying to find sy\frac{\partial{s}}{\partial{y}}

I don't think you know what a differential is. Because if you did, you would have provided me with some insight rather than write out that God forsaken useless 'I don't think you understand...' reply!

Okay, I know that. Care to answer my question?

FFS, why doesn't someone just answer his question?

You can't say what it is without further information.

eg if x=y^2 then it's 2y. If x and y are independent variables, then it's 0.

If x and y are independent variables, then it's 0.


Thank you sir! :hat:

f(x, y) = x. Then fy=limh0f(x,y+h)f(x,y)h=0\frac{\partial f}{\partial y} = \displaystyle \lim _{h\to 0} \frac{f(x, y+h) - f(x, y)}{h} = 0 since f(x, y+h) = f(x, y) = x.
