I'm given this equation:
w= root(u^2 + v^2)
I'm to find all the second order partial derivatives.
Formulas are swirling in my mind and I need someone to show me at least one first and second order partial derivative step by step so I can make sense of the rest of them. I know how to differentiate but its hard to remember all the details. Do I have to use the Chain Rule?
And remember that this is "partial" differentiation so it is close to but not quite the same as ordinary differentiation.
Thanks for the help.
