i too am an engineer but i only took it to the undergrad lvl and am not familiar with this notation... can you clarify?
Show that:
I have Euler's chain rule and "the splitter." Also the property, called the "inverter" where you can reciprocate a partial derivative.
If I write Euler's chain rule, I only know how to write it when there are 3 variables, I usually write it in the form:
Where I can write x,y,z in any order as long as each variable is used in every spot. However, I do not know how to work this chain rule if I have an extra variable (u in this case).
I also tried using the "splitter" to do something like writing:
However, I do not know what to do with this because I have the term
, which doesn't appear in the original problem.
Any help would be appreciated.
Thanks in advance.
(This is for a thermodynamics course, but we are still in the mathematics introduction.)
There's a good argument here about this.

Partial derivative notation
I think that should clear things up about the notation.
