Square root of 2 produce another whole-number square, even when the equation is not in its simplest form. "Proof": Assume formula_40 is rational. Therefore, But the lemma proves that the sum of two identical whole-number squares cannot produce another whole-number square. Therefore, the assumption that formula_40 is rational is contradicted. formula_40 is irrational. Q. E. D. One-half of , also the reciprocal of , approximately , is a common quantity in geometry and trigonometry because the unit vector that makes a 45° angle with the axes in a plane has the coordinates This number satisfies One interesting property of is as follows: since This
