Yah that's the... del operator :o do you want the one with the vector arrow above it..? :o

\frac{ dy }{ dx } = -\frac{\del f /\del x}{\del f/\del y}

i mean like the one used on http://en.wikipedia.org/wiki/Partial_derivative

\[\partial \]

ahhh \partial

\[\huge \vec \nabla f(x,y)=\left<\frac{\partial f}{\partial x}, \frac{\partial f}{\partial y}\right>\]

Yah i been trying to figure out latex the last couple of weeks :) it's kinda interesting
baldymcgee6
  • baldymcgee6
very interesting.. i'm pressured to use it for one of my math classes, i try to avoid it.. :)

  • baldymcgee6
anyways, do you get the question?

  • zepdrix
the nabla thing is the "gradient" of f, it's the direction of greatest increase from a surface. It ummmmmm... i would try to draw a picture but i'm not sure i have the greatest understanding of it myself... :\ hmm

haha, thats okay.. i'll learn that when i get to that.
