Re: Showing the steps

soroban, though differentials are written like this because they behave like multiplication/division most of the time, one can not prove an identity by using arithmetic.

Identity, you sure you have it right?  I am getting that (assuming equality of mixed partials)

Re: Showing the steps

I’m sure Identity’s equation is correct.
