Derivation

  1. Initial program 28.1

    \[\frac{\left(\left(\left(x \cdot y + z\right) \cdot y + 27464.7644705\right) \cdot y + 230661.510616\right) \cdot y + t}{\left(\left(\left(y + a\right) \cdot y + b\right) \cdot y + c\right) \cdot y + i}\]

  2. Applied simplify28.4

    \[\leadsto \color{blue}{\frac{(\left((y \cdot \left((x \cdot y + z)_*\right) + 27464.7644705)_*\right) \cdot \left(y \cdot y\right) + \left((230661.510616 \cdot y + t)_*\right))_*}{(\left((\left(y + a\right) \cdot y + b)_*\right) \cdot \left(y \cdot y\right) + \left((c \cdot y + i)_*\right))_*}}\]
