If q is a function of c, then h becomes a function of one independent variable, and your use of partials here doesn’t make sense, because you can’t hold c constant while changing q or vice versa.
I thought that this was the kind of situation partial derivatives are there for. AlanCrowe’s just applied the multivariable chain rule, if I’m getting it right.

Thanks, you (and Alan) are right. Sorry, it’s been a while.
