    Using Multi-Variable Chain Rule to Prove Equation Involving z = f(x^2 + y^2)

    something like dz/dx = dz/dg dg/dx? (d = that stupid partial sign)

    Classifying Extrema and Saddle Points of Multivariable Functions

    guess ur doing mab127 too when d < 0 its a saddle point doesn't matter what fxx is

    Using Multi-Variable Chain Rule to Prove Equation Involving z = f(x^2 + y^2)

    Homework Statement z = f (x^2 + y^2) prove using multi var chain rule that y * dz/dx - x * dz/dy = 0 Homework Equations The Attempt at a Solution honestly i just need to no how to start it then I am sure i could figure the rest out so i would find dz/dx and dz/dy then...
