WebA unit vector in the direction of a given vector is found by dividing the given vector by its magnitude: A unit vector in the direction of a is given the ‘hat’ symbol ˆa. Key Point 3. A unit vector can be found by dividing a vector by its modulus. ˆa = a a Exercises. Draw an arbitrary vector r. On your diagram draw 2 r, 4 r, −r, − 3 ... In vector calculus, divergence is a vector operator that operates on a vector field, producing a scalar field giving the quantity of the vector field's source at each point. More technically, the divergence represents the volume density of the outward flux of a vector field from an infinitesimal volume around a given point.
