Partial Derivative of w Relative to x

Click For Summary
SUMMARY

The discussion centers on finding the partial derivative of the function w = 2cot(x) + y².z² with respect to x, treating the term y².z² as a constant. Participants clarify that the expressions for y and z, defined as y = sin(uv) and z = e^v, are irrelevant for this specific derivative calculation. The key takeaway is that the derivative of cot(x) is -csc²(x), which is essential for solving the problem.

PREREQUISITES
  • Understanding of partial derivatives

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.
 
Physics news on Phys.org
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.
