Graphs of Trigonometric Functions/TRIGONOMETRY USING THE SHARP EL-9600 1
GRAPHS OF
TRIGONOMETRIC FUNCTIONS
Chapter one
Introducing the Topic
In this chapter, you and your students will learn how to graph trigonometric
functions on the Sharp EL-9600. Graphing trigonometric functions on the
calculator is covered first, so that graphical evaluation of trigonometric
functions may be covered in the next chapter. The trigonometric functions
are often introduced as circular functions with angle measurement in degrees
and radians. The sine and cosine functions are said to map the angle
measurement to the y and x coordinates respectively, of the point on the unit
circle representing the angle. Then, the four additional trigonometric functions
are defined in terms of sine and cosine.
If you let the angle measurement be represented by a horizontal axis (x) and let
the vertical axis (y) represent the function evaluated at the angle, then you can
graph the six trigonometric functions as y = sin x, y = cos x, y = tan x, y = csc x,
y = sec x, and y = cot x.
