Given:
Amplitude = 2
Midline = 5
Period of
.
To find:
The cosine function.
Solution:
The general cosine function is:
...(i)
Where, |A| is amplitude,
is period,
is phase shift and D is the mid line.
Period of function is
. So,



Substituting
in (i), we get


Therefore, the required cosine function is
.
Two equations for a horizontal line could be y = 1 & y = 5
Two equations for a vertical line could be x = 2 & x = 6
Horizontal lines are created when y is always equal to one number, while vertical lines are created when x is always equal to one number.
