Derivation

  1. Initial program 0.1

    \[\left(d1 \cdot \left(\left(\left(\left(\left(d1 \cdot \left(d1 \cdot d1\right)\right) \cdot d1\right) \cdot d1\right) \cdot \left(d1 \cdot d1\right)\right) \cdot d1\right)\right) \cdot d1\]

  2. Applied simplify0.2

    \[\leadsto \color{blue}{{\left(d1 \cdot d1\right)}^{\left(3 + 2\right)}}\]

  3. Taylor expanded around 0 0

    \[\leadsto \color{blue}{{d1}^{10}}\]
  4. Removed slow pow expressions.
