Question
Consider the function given by y = cos(bx) on the interval [o, 2x).
(a) Sketch the graph of y = cos(bx) for b =
2, and 3.
y
27
27
-1
(b) How does the value ofb affect the graph?
The value of b determines the period
and therefore determines the number of cycles
over the interval (0, 2x).
(c) How many complete cycles occur between 0 and 2r for each value of b?
b=
complete cycle(s)
b = 2
complete cycle(s)
b = 3
complete cycle(s)
