INVERSE TRIGONOMETRIC FUNCTIONS |
In previous units, we have made the following observations:
In addition, the “arctangent” was used to find an unknown angle measure given the ratio of two sides of a right triangle. For an equation of the form, y = tan x, the equation represents the ratio of two sides of the triangle given a known angle measure, x.
| By examining these two situations together, it is implied that the functions
are inverse functions in the following manner:
|
In this unit we will examine the relationships that exist between the trigonometric functions and their inverses, how they are identified, and develop graphing techniques to find their characteristic curves.
