I was wondering, how you break down d

**S**to something with dA? I know that d

**S**is equal to

**n**dS. The

**n**is equal to grad f / (magnitude of grad f) and the dS is equal to the same as the magnitude of grad f right? So is the formula the same as double integral of region D (curl F * grad f) dA?
