Fungrim entry: d0c9ff

R_F\!\left(0, y, z\right) = \frac{\pi}{2} R_{-1 / 2}\!\left(\left[\frac{1}{2}, \frac{1}{2}\right], \left[y, z\right]\right)

Assumptions:

y \in \mathbb{C} \setminus \left(-\infty, 0\right] \;\mathbin{\operatorname{and}}\; z \in \mathbb{C} \setminus \left(-\infty, 0\right]

TeX:

R_F\!\left(0, y, z\right) = \frac{\pi}{2} R_{-1 / 2}\!\left(\left[\frac{1}{2}, \frac{1}{2}\right], \left[y, z\right]\right)

y \in \mathbb{C} \setminus \left(-\infty, 0\right] \;\mathbin{\operatorname{and}}\; z \in \mathbb{C} \setminus \left(-\infty, 0\right]
