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)
