Derivation

1. Initial program 7.2

   \[\left(x.re \cdot x.re - x.im \cdot x.im\right) \cdot x.im + \left(x.re \cdot x.im + x.im \cdot x.re\right) \cdot x.re\]

2. Applied simplify0.2

   \[\leadsto \color{blue}{(\left(x.re - x.im\right) \cdot \left(\left(x.re + x.im\right) \cdot x.im\right) + \left(\left(x.re + x.re\right) \cdot \left(x.re \cdot x.im\right)\right))_*}\]

4. Applied add-cube-cbrt0.6

   \[\leadsto (\left(x.re - x.im\right) \cdot \left(\left(x.re + x.im\right) \cdot x.im\right) + \left(\color{blue}{\left(\left(\sqrt[3]{x.re + x.re} \cdot \sqrt[3]{x.re + x.re}\right) \cdot \sqrt[3]{x.re + x.re}\right)} \cdot \left(x.re \cdot x.im\right)\right))_*\]

5. Applied associate-*l*0.6

   \[\leadsto (\left(x.re - x.im\right) \cdot \left(\left(x.re + x.im\right) \cdot x.im\right) + \color{blue}{\left(\left(\sqrt[3]{x.re + x.re} \cdot \sqrt[3]{x.re + x.re}\right) \cdot \left(\sqrt[3]{x.re + x.re} \cdot \left(x.re \cdot x.im\right)\right)\right)})_*\]

6. Taylor expanded around 0 35.4

   \[\leadsto \color{blue}{\left({x.re}^{2} \cdot x.im + x.re \cdot \left(e^{\log x.re + \log 2} \cdot x.im\right)\right) - {x.im}^{3}}\]

7. Applied simplify0.3

   \[\leadsto \color{blue}{(\left(-x.im\right) \cdot \left(x.im \cdot x.im\right) + \left(\left(x.im \cdot x.re\right) \cdot (x.re \cdot 2 + x.re)_*\right))_*}\]
