Derivation

  1. Initial program 0.1

    \[0.954929658551372 \cdot x - 0.12900613773279798 \cdot \left(\left(x \cdot x\right) \cdot x\right)\]

  2. Initial simplification0.1

    \[\leadsto (\left(-0.12900613773279798\right) \cdot \left({x}^{3}\right) + \left(0.954929658551372 \cdot x\right))_*\]

  3. Final simplification0.1

    \[\leadsto (\left(-0.12900613773279798\right) \cdot \left({x}^{3}\right) + \left(x \cdot 0.954929658551372\right))_*\]
