Completely fair point, that I do not think I have the knowledge to speak on. On the Trigonometry Wikipedia page, he pops up a few times, and many trig identities are known as pythagorean identities. Perhaps its not fully trig, but was used as a basis to help discover trig? Without having the understanding pythagorus gave mathematicians regarding triangles, I would think it would be pretty hard to begin developing deeper math regarding said triangles
Squaring using 3+4=5 is one of the oldest relationships used by masons. don’t need a ruler, just a piece of string or straight edge. Pythagoras described the relationship on paper
Did Pythagoras even know about sin, cos and tan? I am reluctant to call A^2 +B^2 =C^2 trigonometry.
Hipparchus, the alleged founder of trigonometry, was alive 350 years after Pythagoras (500BC to 150BC).
