Trigonometry Review Day 1
Primary Trig Ratios of a Right angle triangle
and Reciprocal Trigonometric Ratios
Review the method of applying primary
trig ratios (tan, cos, sin) within a right
angle triangle and how to “solve” a
triangle.
csc, secant and cot ratio in a right triangle
Understanding Angles

Definitions of angles in a Cartesian plan.
Related Acute Angle
We will learn to find the conterminal
angles larger than 360 degrees or smaller
than 0 degree.
