\[ {d1}^{10} \]

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 simplify 0.2

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

  3. Applied taylor 0

    \[\leadsto {d1}^{10}\]

  4. Taylor expanded around 0 0

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