Best ResponseYou've already chosen the best response.1There are three independent variables given that f(x,y,z) = xz + ylnx + x^2 + 4 how do you intent to define x and function of independent variable 'x' and 'y'

Best ResponseYou've already chosen the best response.1apparently you can put f(x,y,z) = some constant ... sill separating x from those values is quite difficult

Best ResponseYou've already chosen the best response.1still separating x out of ln(x) is quite a challenge. while you can do the last part

Best ResponseYou've already chosen the best response.0how can i separate x from lnx do you have any concept to do that?

Best ResponseYou've already chosen the best response.1the last part requires that ... for separation of x, PDE is the best guess,

Best ResponseYou've already chosen the best response.0about find the value in the last part i know how to solve it, but about define x as differentiable function of two independent variable y and z i still not clear
