Trig
The study of triangles, with emphasis on calculations involving
the lengths of sides and the measures
of angles. Trigonometry is
also known as trig.
Trigonometry is based on the six functions sine, cosine,
tangent, cosecant, secant, and cotangent.
Trig also includes studies of the properties of these functions
and their
graphs.
Finally, trig involves the analysis of circles and periodic
motion.
