Query: New proofs of Borwein-type algorithms for Pi   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 $1/\pi$. We will not use the modular theory nor either the
Gauss' formula that we used in another paper. Our proofs are short and
self-contained.
