Hello
I have a question:
Let w=2cot x +y^2.z^2
x = uv
y = sin(uv)
z = e^v
Find the partial derivative of w releative to x.

Treat y^2.z^2 as a constant and derive with respect to x (the y^2.z^2 term will disappear). If you need any more help please post what you tried to do :).

PS. Partial derivatives aren't really pre-calculus :P

That's a pretty straight forward problem. You may be thinking it is harder than it is because, since u, v, and w are not present in the problem, the information you give: x=uv, y= sin(uv), z= ev is irrelvant. Please show us what you have done. In particular, what is the derivative of tan(x)?

As focus said, this is not at all "precalculus". I am going to move this to the "calculus and beyond" homework area.
 

1. What is a partial derivative of w relative to x?

A partial derivative of w relative to x is a measure of how much w changes with respect to a small change in x, while holding all other variables constant. It is used in multivariate calculus to analyze the rate of change of a function with multiple variables.

2. How is a partial derivative of w relative to x calculated?

A partial derivative of w relative to x is calculated by taking the derivative of the function with respect to x, treating all other variables as constants. This is typically denoted as ∂w/∂x.

3. What is the interpretation of a partial derivative of w relative to x?

The interpretation of a partial derivative of w relative to x is the slope of a tangent line to the curve of the function w in the direction of the x-axis. It represents the rate of change of w in the direction of x, while keeping all other variables constant.

4. When is a partial derivative of w relative to x used?

A partial derivative of w relative to x is used in situations where a function has multiple variables and we want to analyze how the function changes with respect to one specific variable, while holding all others constant. It is commonly used in economics, physics, and engineering.

5. Can a partial derivative of w relative to x be negative?

Yes, a partial derivative of w relative to x can be negative. This indicates that as x increases, w decreases, and vice versa. The sign of the partial derivative can provide information about the direction and magnitude of the change in w with respect to x.
