There are four main components in graphing this function:
Explanation:
- Amplitude - twice the
y distance from maximum to minimum - Period - the
x distance between a repetition of the values - Horizontal Phase Shift - the shift on the
x axis - Vertical Phase Shift - the shift on the
y axis
In the function
- Amplitude =
a - Period =
(2pi)/b - Horizontal Phase Shift =
c/b - Vertical Phase Shift =
d
Thus you can figure out:
- Amplitude =
4 - Period =
pi - Horizontal Phase Shift =
-pi/2 - Vertical Phase Shift =
3
Note:
The amplitude is always positive because distances can not be negative. When the
When you graph this function you will get:
graph{-4*cos(1/2x-pi)+3 [-9.46, 10.54, -1.76, 8.24]}
