(adsbygoogle = window.adsbygoogle || []).push({}); grad, curl , div operator got any meaning??

∇xF(t) same as the first derivative ofFwith respect to t , or will get the gradient ofFwhich is normal to theF?

∇ dotF(t) , will get the scalar value of what??

lets sayFis force , then can anyone please give me the meaning of those operator on the vector mean?

∇xF(t) will get the gradient ofFwhich is normal to theF.

I think of this because in the stoke's theorem the ∇xF(t) have to dot withn, wherenshould be the unit normal vector of the surface.

I am blur , please guide .

Thank you.
