Derivation

1. Initial program 99.8%

   \[x \cdot \cos y - z \cdot \sin y \]
2. Add Preprocessing

3. Taylor expanded in y around 0 53.2%

   \[\leadsto \color{blue}{x + -1 \cdot \left(y \cdot z\right)} \]
4. Step-by-step derivation

   1. mul-1-neg 53.2%

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

   2. unsub-neg 53.2%

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

   3. *-commutative 53.2%

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

5. Simplified 53.2%

   \[\leadsto \color{blue}{x - z \cdot y} \]
6. Add Preprocessing
