Use the graph of the sine function. Can someone help me with it?
1 Answer
a.
b.
c.
Please see the explanation.
Explanation:
Part a.
There is only 1 way to obtain this answer.
Look at the graph and observe that there is only 1 complete cycle.
Part b.
There are 2 ways to obtain this answer.
-
Look at the graph and observe the value of x where the cycle completes.
x = 2pi , therefore, the"Period" = 2pi -
Referring the form
y = Asin(Btheta) and the formula
We observe that the value of
Part c.
There are several ways to obtain this answer; I shall give 2.
-
Look at the graph and observe that it start at 0 and achieves a maximim of 2; this means that the
"Amplitude" = 2 -
Referring the form
y = Asin(Btheta) and the formula
We observe that the value of
