First of all, thank you for your kind words.

It is true that ancient greeks didn't know almost anything about trigonometry, but they presented their theories in a geometric way that was equivalent to some trigonometric laws and formulas..

For example, there is Aristarchus' inequality, trigonometric law, although Aristarchus didn't posses any knowledge on trigonometry, not to speak about notation, but he was using that law in a more lets say geometric way..

And yes, ancient greeks, without doubt, used primitive math and physics...for example their best argument for non spinning Earth was 'if I jump I will land on a different place, but I am landing always in the same place therefore Earth is static' but they didn't know whatwhat is inertia back then :)
