Hello.

I need to find the partial derivative with regards to variables in a list.

The straight forward syntax would be
D[f[a,b,c,d,e,],a,b,c,d,e]

My problem is that I don't know the variables up front of finding the
derivative.

I've tried Apply[], but as I am quite new to Mathematica, I haven't been
able to use Apply[] with functions with more than one argument.

Please advice.
