- Proposes an elementary and accurate approximation for Euler’s totient φ(n) for semiprime n = pq with large primes p, q.
- Derivation based on Euler–Fermat theorem and quadratic symmetry of n.
- Approximation shows decreasing relative error as n grows and p, q become more balanced.
- Includes a closed error identity, simple bounds, and numerical evidence.
