WebWe can take the divergence of this field using the expression in Section 14.4 for the divergence of a radial vector field, which yields \begin{gather*} \grad\cdot\EE = \frac{1}{r^2} \Partial{}{r}\Bigl(r^2 E_r\Bigr) = \frac{1}{4\pi\epsilon_0} \Partial{q}{r} = 0 \end{gather*} WebThey have different formulas: The divergence formula is ∇⋅v (where v is any vector). The directional derivative is a different thing. For directional derivative problems, you want to find the derivative of a function F(x,y) in the direction of a vector u at a particular point (x,y). It can be any number of dimensions but I'm keeping it x,y for simplicity.
