HW: Pg 416-417 #9-16 and 38-44 all

TODAY: continuing our work with sine, cosine and tangent...they are functions, not quantities. They are rules that take in angle measures and then output ratios. HOW? see the definition...see me too!

sin x = opposite side/hypotenuse

cos x = adjacent side/hypotenuse

tan x = opposite side/adjacent side

where x is one of the acute angles in a right triangle!
