Derivation

  1. Initial program 10.2

    \[\frac{x + y \cdot \left(z - x\right)}{z}\]

  2. Taylor expanded around 0 3.4

    \[\leadsto \color{blue}{\left(\frac{x}{z} + y\right) - \frac{x \cdot y}{z}}\]

  3. Simplified3.4

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

  5. Applied div-sub3.4

    \[\leadsto y - \color{blue}{\left(\frac{x \cdot y}{z} - \frac{x}{z}\right)}\]

  6. Taylor expanded around 0 3.4

    \[\leadsto y - \left(\color{blue}{\frac{x \cdot y}{z}} - \frac{x}{z}\right)\]

  7. Simplified0.0

    \[\leadsto y - \left(\color{blue}{y \cdot \frac{x}{z}} - \frac{x}{z}\right)\]

  8. Final simplification0.0

    \[\leadsto y - \left(y \cdot \frac{x}{z} - \frac{x}{z}\right)\]
