Solving Partial Derivatives: x2+y2+z2=3xyz

In summary, the conversation involved finding the partial derivatives of zx, zy, and zxy for the equation x2+y2+z2=3xyz. The person was unsure if they needed to isolate z in the equation and asked for help. They later figured out the solution using implicit differentiation and thanked everyone for their assistance.

x2+y2+z2=3xyz
Find the partial derivatives: zx, zy, and zxy.


Okay so I know how to find the partial derivative, but I am not sure as to if I need to get the z on one side by itself. If that is what I need to do, then I am actually unsure as to how. I attempted to isolate z and ended up with z=[tex]\frac{x^{2}+y^{2}}{3xy-z}[/tex].

If I need to isolate z, then that is what I need help in doing. I know how to find the partial derivatives so I'm good there, but the zx, etc., is just kind of confusing since he never went over anything like this in class and the book doesn't have it, either (it always has fx).

The partial derivatives are as follows: z_x=\frac{2x}{3xy-z} z_y=\frac{2y}{3xy-z} z_{xy}=\frac{2}{3xy-z}
 

FAQ: Solving Partial Derivatives: x2+y2+z2=3xyz

What is the formula for solving partial derivatives?

The formula for solving partial derivatives is to take the derivative of the function with respect to one variable while treating all other variables as constants.

How do you solve partial derivatives using the given equation x2+y2+z2=3xyz?

To solve partial derivatives using the given equation, you would first need to isolate one variable on one side of the equation. Then, take the derivative of the equation with respect to that variable. Repeat this process for each variable in the equation.

What is the purpose of solving partial derivatives?

The purpose of solving partial derivatives is to determine the rate of change of a function with respect to one variable, while treating all other variables as constants. This is useful in many fields, such as physics, engineering, and economics.

Can you use the chain rule when solving partial derivatives?

Yes, the chain rule can be used when solving partial derivatives. This is helpful when the function is composed of multiple functions, and you need to take the derivative with respect to one of the inner functions.

Are there any tips for solving partial derivatives?

One tip for solving partial derivatives is to make sure you are following the rules of differentiation, such as the product rule and chain rule. It is also important to be careful with algebraic manipulations to avoid mistakes. Lastly, it can be helpful to practice solving partial derivatives with various functions to improve your skills.
