Hi guys,

problem goes like this,

proof curl(u+v)=curl u + curl v

I assume u and v are 2 different vector fields... and have sufficient differentiability

Is there a way to do this without expanding the cross product?

Also, when adding vector fields like u+v

is it the same as when you add normal vectors?

say u=(ai+bj+ck) and v=(di+ej+fk) does u+v=(a+d)i+(b+e)j+(c+f)k ???

what is the graphic representation of adding vector fields?? Is it just adding every two vectors of the same co-ordinates together?
