In the 1760s, Johann Heinrich Lambert was the first to prove that the number π is irrational, meaning it cannot be expressed as a fraction $${\displaystyle a/b}$$, where $${\displaystyle a}$$ and $${\displaystyle b}$$ are both integers. In the 19th century, Charles Hermite found a proof that requires no prerequisite … Meer weergeven In 1761, Lambert proved that π is irrational by first showing that this continued fraction expansion holds: Then Lambert proved that if x is non-zero and rational, … Meer weergeven This proof uses the characterization of π as the smallest positive zero of the sine function. Suppose that π is rational, i.e. π = a /b for some integers a and b ≠ 0, which may be taken without loss of generality to be positive. … Meer weergeven Miklós Laczkovich's proof is a simplification of Lambert's original proof.
