Derivation

  1. Split input into 4 regimes

  2. if (cbrt (/ z y)) < -2.608850838893404e+74 or -2.0009800614308152e-90 < (cbrt (/ z y)) < 5.597701311680432e-74

    1. Initial program 29.4

      \[x \cdot \frac{\frac{y}{z} \cdot t}{t}\]

    2. Applied simplify19.8

      \[\leadsto \color{blue}{\frac{x}{\frac{z}{y}}}\]

    3. Taylor expanded around 0 0.7

      \[\leadsto \color{blue}{\frac{y \cdot x}{z}}\]

    if -2.608850838893404e+74 < (cbrt (/ z y)) < -2.0009800614308152e-90

    1. Initial program 9.0

      \[x \cdot \frac{\frac{y}{z} \cdot t}{t}\]

    2. Applied simplify0.2

      \[\leadsto \color{blue}{\frac{x}{\frac{z}{y}}}\]

    if 5.597701311680432e-74 < (cbrt (/ z y)) < 2.4351802450022884e+82

    1. Initial program 8.5

      \[x \cdot \frac{\frac{y}{z} \cdot t}{t}\]

    2. Applied simplify0.2

      \[\leadsto \color{blue}{\frac{x}{\frac{z}{y}}}\]

    if 2.4351802450022884e+82 < (cbrt (/ z y))

    1. Initial program 17.7

      \[x \cdot \frac{\frac{y}{z} \cdot t}{t}\]

    2. Applied simplify13.3

      \[\leadsto \color{blue}{\frac{x}{\frac{z}{y}}}\]
    3. Using strategy rm

    4. Applied associate-/r/0.2

      \[\leadsto \color{blue}{\frac{x}{z} \cdot y}\]
  3. Recombined 4 regimes into one program.
