    Es handelt sich um den gemeinsamen Grenzwert der Zahlen \(a_n\) und \(b_n\), wenn \(a_{n+1} =\frac12(a_n +b_n)\), \(b_{n+1} = \sqrt{b_n \cdot a_{n+1}}\) ist. Sind die reellen Teile von \(\dfrac{b_n}{a_n}\) von einem bestimmten \(n\) an positiv, so ist der Grenzwert gleich \(\dfrac{b\sin z}{bz}\), wo \(a = b \cos z\) ist, sonst (abgesehen von gewissen Ausnahmefällen) gleich 0.
