∫∫ F(r(s,t))⋅(r

_{s}x r

_{t})*dA

but in physics for Gauss's law it is

∫∫E⋅nhat dA

How are these the same basic formula? I know that nhat is a unit vector, so it is n/|n|, but in the actual equation, it is a dot between the cross product and E.

The problem is I don't know how they are the same since Gauss' Law wants E dot a magnitude, when a surface integral is F dot the vector cross product? They don't seem to be following the same rules
