## divergence of a vector field

Im just curious how you find the divergence of the following vector field

Heres my example

u = xz^(2)i +y(x^(2)-1)j+zx^(2) y^(3)k

Am I right in thinking

U take the derivative with respect to x for first term derivative with respect to y for second term......

giving me z^(2) + (x^(2) -1) +x^(2)y^(3)

 Thanks LCKurtz just another question I have bin posed. does div(uxv) Mean find the divergence of the dot product of vectors u and v.

## divergence of a vector field

 Quote by andrey21 Thanks LCKurtz just another question I have bin posed. does div(uxv) Mean find the divergence of the dot product of vectors u and v.
No. That wouldn't make any sense because a dot product gives a scalar and divergence applies to vector fields. What it does mean is first take the cross product of a and b, which gives a vector, then take its divergence.
