Derivation

  1. Initial program 15.5

    \[\sqrt[3]{\frac{g}{2 \cdot a}}\]
  2. Using strategy rm

  3. Applied cbrt-div0.9

    \[\leadsto \color{blue}{\frac{\sqrt[3]{g}}{\sqrt[3]{2 \cdot a}}}\]
  4. Using strategy rm

  5. Applied clear-num0.9

    \[\leadsto \color{blue}{\frac{1}{\frac{\sqrt[3]{2 \cdot a}}{\sqrt[3]{g}}}}\]

  6. Taylor expanded around inf 48.7

    \[\leadsto \frac{1}{\color{blue}{{\left(\frac{1}{g}\right)}^{\frac{1}{3}} \cdot e^{\frac{1}{3} \cdot \left(\log 2 - \log \left(\frac{1}{a}\right)\right)}}}\]

  7. Applied simplify0.9

    \[\leadsto \color{blue}{\frac{\frac{1}{\sqrt[3]{\frac{1}{g}}}}{\sqrt[3]{2 \cdot a}}}\]
