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
