this is the figure they provided but where did they get the q and r? and 7 for that matter? I am confused....
OpenStudy (btaylor):
make triangle relations. sin = opposite/hypotenuse, tan=opposite/adjacent, cos=adjacent/hypotenuse. So:|dw:1339706553045:dw|By that, cos y = r/q
OpenStudy (anonymous):
that makes so much more sense why couldnt they have done that??
OpenStudy (btaylor):
they want to see you analyze the side relationships of trig functions.
