We use a method of translation to recover Borweins' quadratic and quartic iterations. Then, by using the WZ-method, we obtain some initial values which lead to the limit . We use neither the modular theory nor the formula of Gauss that we used in another paper. Our proofs are short and self-contained.
Many thanks to Jonathan Sondow for improving my sometimes awkward English.
