Knowledge and understanding are quite different. Only understanding can lead to being, whereas knowledge is but a passing presence in it. (G.Gurdjieff)

$(\boldsymbol{p}\cdot\nabla\boldsymbol{p})_\alpha=p_\beta\partial_\beta p_\alpha$

comment Orthogonal Part Operator
No, I simply meant the application of $P$ to those terms: $P(\boldsymbol{p}\cdot\nabla\boldsymbol{p})$

comment Orthogonal Part Operator
Yes, I need to be clearer. $\boldsymbol{p}$ is a column vector of $\mathbb R^3$, function of $\boldsymbol{x}$, respect to which the differentiation in $\nabla$ is carried. The $P$ operator is exactly the matrix $P_{\alpha\beta}=\delta_{\alpha\beta}-p_\alpha p_\beta$

comment Closed form with of a series Mathematica
Yes, but what about the closed form if $x$ can be every value, so not necessarily $0<x<x_0$?

Added input code and yes $A=x_0$, $B=h$!
