Compute the divergence of (z - x2)i - yj + sin(x)k.

What do I do?

Take the x derivative of the i coefficient, the y derivative of the j coefficent and the z derivative of the k coefficient and add these up.
We get - 2x - 1 here.
Always remember that the divergence is a number or a numerical function; it is not a vector.
