Agreement of the primary approximation of function ArcTra with
$\mathrm{ArcTra}(z)\approx $ $\mathrm{app3}(z)=$ $ \displaystyle \ln(z) \left(1+ \frac{1}{z} \sum_{m=0}^M \frac{P_m(\ln(z))}{z^m}\right)$
$P_0(L)=-1$
$P_1(L)=1-L/2$
$P_2(L)=-1+3 L/2 -L^2/3$
$P_3(L)=1-3L+11L^2/6-L^3/4$
$P_4(L)=-1+5L-35L^2/6+25L^3/12-L^4/5$
For $M\!=\!4$, the agreement $A=A_3(x+\mathrm i y) $ is shown;
$\displaystyle \mathcal A_3(z)= $ $\displaystyle -\lg \left( \frac{ |\mathrm{tra}(\mathrm{app3}(z))-z| }
{ |\mathrm{tra}(\mathrm{app3}(z))| + |z|}
\right)$
