Section 5-I.3 – Trigonometric Ratios
Section Learning Objectives
After completing this section
you should be
able to:

definitions of the
six trig ratios
- Find the values of
all six trig
ratios for an any angle in a right angled triangle whose side lengths
are
specified (or even if just two are)
- Recognize special
cases of
angles whose trig ratios can be determined exactly in terms of radicals
by
using basic geometry
- Use a calculator or
tables to
determine approximate trig ratios for any given angle

the sides of a
right triangle given one side and one of the acute angles
