Derivation

1. Initial program 99.9%

   \[\left(x + \cos y\right) - z \cdot \sin y \]
2. Add Preprocessing

3. Taylor expanded in y around 0

   \[\leadsto \color{blue}{1 + x} \]
4. Step-by-step derivation

   1. lower-+.f64 61.4

      \[\leadsto \color{blue}{1 + x} \]

5. Applied rewrites 61.4%

   \[\leadsto \color{blue}{1 + x} \]

6. Taylor expanded in x around 0
