Finding the Implicit Partial Derivative (∂y/∂x)z for x3 + y3 + z3 - 3xyz = 6

Click For Summary
SUMMARY

The discussion focuses on finding the implicit partial derivative (∂y/∂x)z for the equation x³ + y³ + z³ - 3xyz = 6. Participants confirm that it is appropriate to take the partial derivative of both sides while treating z as a constant. The equation is reformulated as f(x,y,z) = 0, leading to the conclusion that (∂f/∂x)z = 0 accurately represents the relationship, with y considered a function of x alone.

Homework Statement



x3 + y3 + z3 - 3xyz = 6

Find (∂y/∂x)z.

Homework Equations





3. The Attempt at a Solution [/

can i simply take the partial derivative of both sides treating z as constant?

x3 + y3 + z3 - 3xyz - 6 = 0

f(x,y,z) = 0

(∂f/∂x)z = 0

Yes.
 
That z is to be held constant and y thought of as a function of x only is precisely what that subscript "z" means.
