I believe that calculators use Taylor expansions to compute sines, cosines and tan's based upon the argument [itex]\theta[/itex] (in radians of course). However, my question is, aside from these expansions, is there some sort of link between [itex]\theta[/itex] and the output of the function itself.(adsbygoogle = window.adsbygoogle || []).push({});

I mean I know that [itex] \cos{\theta} = \frac {adj}{hyp}[/itex] and the other trig ratios, but was this just worked out by hand, pencil and paper and kept in a tabular form before the Taylor expansion was devised? Is there a direct link between [itex] (\frac{adj}{hyp}) [/itex] and [itex]\theta[/itex].

Get me?!
