Say we have the coordinate transformation [tex]\bf{x}' = \bf{x} + \epsilon \bf{q}[/tex], where [tex]\epsilon[/tex] is constant. (And small if you like.) Then obviously

[tex]d \bf{x}' = d \bf{x} + \epsilon d \bf{q}[/tex].

How do we find [tex]\frac{d}{d \bf{x}'}[/tex]?

I'm missing something simple here, I'm sure of it.
