\[w = x ^{2} + y - z + \sin(t)\] \[x + y = t\] Sorry which derivative are you looking for?
anonymous
  • anonymous
we have to find \[(dough w/dough y)_{x,z}\].partial derivative

I'm honestly not sure what you mean by that notation.

there's no notation here, consider dough = d (dw/dx)\[_{x,z}\]

(\[(dw/dx)_{x,z}\] what does this x,z mean here?
anonymous
  • anonymous
sry , it is \[(dw/dy)_{x,z}\]
anonymous
  • anonymous
use \partial to get \[\partial\] if you like

thanks eb... can u temme wat foes 'x,z' mean here?
anonymous
  • anonymous
\[(\partial w/ \partial y)_{x,z}\] --------this is the actual notation
anonymous
  • anonymous
Okay I think that means find the derivative of w with respect to y, and evaluate at x,z? Not exactly sure
anonymous
  • anonymous
i wanted to know what this x,z means...i guess those are independent variables? is it?
anonymous
  • anonymous
w=x2+y−z+sin(t) x+y=t w=x2+y−z+sin(x+y) assuming w=f(x,y,z) (dw/dy) =0+1+0+cos(x+y) =1+Cos(x+y)
