Hi tiny-tim and LCKurtz, This is exactly the explanation I am looking for! I had a hard time to understand the meaning of such partial derivative. And it with \partial it should be :smile: It is the rate of F in the direction of some unit vector n that is normal to an arbitrary surface. I...

Hi, I have a problem to find the meaning of a special partial differential: partial scalar partial vector. i.e. dF/dn where F is a scalar and n is a i.e. normal vector. This is a partial diff. n could be a vector consisting of partial differentials, (dT/dx,dT/dy) I have looked in...
