chapter 13 trig

the ratios of a right triangles 3 sides

find all sides and all angle measures

the angle an object moving upward makes

the angle an object moving downward creates

the starting point for an angle

the end line of an angle

an angle in which both sides are positive is in standard position

two angles in standard position are coterminal

a region of a circle bound by two radii

angle formed by two radii

the terminal side of the angle lands on an axis

always acute, always positive, formed by the terminal side.

sin ^-1

cos^-1

tan^-1
