Hmm, I assumed I could pull the t out of \( \text{D}_{w+t} \), since t is a constant, but now I'm not so sure. My calculus is pretty rusty.
\(
\frac{\text{d}}{\text{d}\left(w+t\right)}\ =\ \frac{\text{d}w}{\text{d}\left(w+t\right)}\frac{\text{d}}{\text{d}w}
\)
If my understanding is correct, dw/d(w+t) should equal 1. Yes?
