Experts:

It's been a while since I modified equations to determine partial derivatives.

Please see attached Word document where I'm solving for partial derivatives of D, T, and S.

I've marked the terms in yellow for each partial derivative.    Could someone please validate that I've done it correctly?   If not, please correct it where necessary.

Thanks,
EEH

That all seems correct.

You don't have to rewrite the equation for the (S-35) terms unless there is an exponent >1.
The  -35 goes away when you take the derivative.

As long it is correct, I'm ok w/ rewriting it.

Thanks for the feedback.
