Derivation

  1. Initial program 18.5

    \[\sqrt{0.5 \cdot \left(1 + \frac{1 - \frac{r}{q}}{\sqrt{p \cdot p + {\left(1 - \frac{r}{q}\right)}^{2}}}\right)}\]

  2. Final simplification18.5

    \[\leadsto \sqrt{0.5 \cdot \left(1 + \frac{1 - \frac{r}{q}}{\sqrt{p \cdot p + {\left(1 - \frac{r}{q}\right)}^{2}}}\right)}\]
