Partial Derivative of z=[x^2 tan^-1(y/x)]-[y^2 tan^-1(x/y)] with Respect to y

Click For Summary
SUMMARY

The discussion focuses on calculating the partial derivative of the function z = [x² tan⁻¹(y/x)] - [y² tan⁻¹(x/y)] with respect to y. Participants emphasize the use of product and chain rules for differentiation. It is noted that the two terms in the function exhibit symmetry, allowing for simplification by calculating one derivative and applying the interchange of variables to find the other. This approach streamlines the process of finding the partial derivative z[xy].

given that z=[x^2 tan^-1(y/x)]-[y^2 tan^-1(x/y)].find value of [z][xy].
where [z][xy] stand for partial derivative w.r.ty(partial derivative of z w.r.tx)

That's not really a question, is it? Just start taking the derivatives. Use the product and chain rules. You can make life a little easier by noticing the two terms are related by an interchange of x<->y. So you could just do one and use that to figure out what the other one is.
