Symbol
$F_{ij}$
Formulae
$\frac{0.5 \left(\pi - \sqrt{c_{ij}^{2} - \left(r_{ij} - 1\right)^{2}} + \sqrt{c_{ij}^{2} - \left(r_{ij} + 1\right)^{2}} + \left(r_{ij} - 1\right) \arccos{\left(\frac{r_{ij} - 1}{c_{ij}} \right)} - \left(r_{ij} + 1\right) \arccos{\left(\frac{r_{ij} + 1}{c_{ij}} \right)}\right)}{\pi}$
