Nested partial derivative operators in Wolfram Language

Posted 11 years ago

Hello,

I am trying to evaluate some nasty derivatives for my splitting scheme. When I tried to do that with Mathematica, I encountered a problem with evaluating an expression of the form below and got an error message.

enter image description here

I would appreciate if anyone could point out how to get the syntax in the first line right in order for Mathematica to evaluate it like the second line.

Thanks, Peter

Simple code input:

In[1]:= f[x] D[g[x, v], v] + v D[g[x, v], x]
