Derivation

  1. Initial program 0.0

    \[\left(x + \sin y\right) + z \cdot \cos y \]

  2. Applied egg-rr0.6

    \[\leadsto \color{blue}{\mathsf{fma}\left(\cos y \cdot {\left(\sqrt[3]{z}\right)}^{2}, \sqrt[3]{z}, x + \sin y\right)} \]

  3. Applied egg-rr0.0

    \[\leadsto \color{blue}{\mathsf{fma}\left(\cos y, z, \sin y\right) + x} \]

  4. Final simplification0.0

    \[\leadsto \mathsf{fma}\left(\cos y, z, \sin y\right) + x \]
