Vieta's Formula for Pi: Also known as

Vieta's formula for pi is also known as Vieta's product, or Viète's product.

Some sources refer to it merely as Vieta's formula, or Viète's formula, but this can be confused with Viète's formulas in the context of polynomial theory.

The form Viète's formula for pi can of course also be seen.
