Cotangent

A primitive Pythagorean triple (PPT) is one in which a, b and c are pairwise coprime.

There is a great formula that will generate an infinite number of Pythagoren Triples that are integers (not fractions).

You get the Pythagorean Triple (10,24,26)

Substituting those numbers into the Pythagorean Theorem:

10^{2}+24^{2}=26^{2} 100+576=676 676=676
