Derivation

1. Split input into 2 regimes

2. if a < -7.499999999999999e176 or 9.4999999999999999e-32 < a

   1. Initial program 84.2%

      \[x + \frac{y \cdot \left(z - t\right)}{z - a} \]
   2. Add Preprocessing

   3. Taylor expanded in x around inf

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

   5. Applied rewrites 67.0%
