    It tells you the rate of change of the intersection with respect to x. dz/dx= (0.5(8-2x^2)^-0.5)*(-4x)

    Parametric equations from partial derivatives

    Okay so then the equation of the intersecting curve is: z=f(x,y)=√(9-2x^2-1)? But how does that help me?

    Parametric equations from partial derivatives

    Thank you, SammyS! And okay, I don't know what that means. A big part of my problem I'd say is understanding math speak. If all I have is numbers then I can do about anything, but throw some words in there and I am completely lost. So what exactly does that mean? Like using different...
