Yes, conventionally, i, j, and k are dimensionless unit vectors pointing, respectively, in the +x, +y and +z directions. Aug 29, 2011 #3 1MileCrash 1,338 41 Alright, got it. Now I am asked for magnitude and direction of new vector. After adding these, I found magnitude to be...
Unit Vectors View Solution Given thati−j,i−2jare two vectors. Find a unit vector coplanar with these vectors and, perpendicular to the first vectori−j. Find also the unit vector which is perpendicular to the plane of the two given vectors. ...
We present a simple notation for performing differential vector operations in orthogonal curvilinear coordinates, and for easily obtaining partial differential expressions in terms of the physical components. We express n th-order tensors as the summed products of the physical components and n th-order...

If ψ is a column vector, then you can write it in Dirac notation as |ψ⟩, where the |⋅⟩ denotes that it's a unit column vector, for example, a ket vector. Similarly, the row vector ψ† is expressed as ⟨ψ|. In other words, ψ† is obtained by applying entry-...
We match the 1st members (1 and 7), multiply them, likewise for the 2nd members (2 and 9) and the 3rd members (3 and 11), and finally sum them up.In effect, the dot product "projects" one vector on to the other before multiplying the lengths:Like...
