p(1, 0) corresponds to
(, ) on the cosine graph.
p(0, 1) corresponds to
(, ) on the cosine graph.
p(−1, 0) corresponds to
(, ) on the cosine graph.
p(0, −1) corresponds to
(, ) on the cosine graph.

Step-by-step explanation:

The cartesian graph consists of x and y axes, while the cosine graph is made of and y axes. This means that each value of x has to be converted in to represent a corresponding point in cosine graph.

Thus,

x = cos

or,

For point (1, 0)

y = cos

y = cos(0)

y = 1

Point in cosine graph = (0, 1)

For point (0, 1)

y = cos

y = cos(90)

y = 0

Point in cosine graph = (90, 0)

For point (-1, 0)

y = cos

y = cos(180)

y = -1

Point in cosine graph = (180, -1)

For point (0, -1)

y = cos

y = cos(90)

y = 0

Point in cosine graph = (90, 0)
