We have seen one way of writing pythagorean triplets as 2m, m² -1, m² 1. A pythagorean triplet a, b, c means a² b² = c². If we use two natural numbers m and n (m greater than n), and take a = m² -n², b = 2mn, c = m² n², then we can see that c² = a² b². Thus for different values of m and n with m greater than n we can generate natural numbers a, b, c such that they form Pythagorean triplets. For...
