How do you graph # y=2cos5x#?
Graph a cosine function with an amplitude of
This equation is in the form
Amplitude is the distance on the y-axis between the center line of the graph and the "peak" or "trough".
Period is the distance on the x-axis of one full "cycle" or "repeat" of the graph.
Let's start with
Next, let's graph
Last, let's look at
In other words, one complete "cycle" of cosine is graphed between zero and
