WebThe proof is generally attributed to the ancient Greek mathematician Hippasus, who is said to have proved the irrationality of pi around 500 BCE. First of all, let us assume that pi is a rational number, which means that it can be expressed as a/b, where a and b are integers with no common factors. 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 … See more 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, then … See more This proof uses the characterization of π as the smallest positive zero of the sine function.
