^{2}f/∂x∂y but I've now become confused about something. If I have a function of 3 variables eg. f(x,y,z) and I calculate ∂

_{x}then I am differentiating wrt x while holding y and z constant. Does that mean ∂

_{x}then becomes a function of x only ie does ∂

_{x}f(x,y,z) = φ( x ) ? If it does then ∂

_{y}and ∂

_{z}will always be zero but I know this is not the case. I'm confused !
