The cordinates of the graph are (π, -0.7071) (2π, 0.7071) (3π,-0.7071) similarly for (-π, -0.7071) (-2π, 0.7071)
Step-by-step explanation:
The function f(x)= cos(x-45)
Can be written as y=cos(x-45)
To find the coordinates of the provided function we proceed by taking the value of x as given below in the table
f(x)= cos(x-45)
Value of “x” f(x)
π -0.7071
2π 0.7071
3π -0.7071
4π 0.7071
5π -0.7071
-π -0.7071
-2π 0.7071
-3π -0.7071
-4π 0.7071
-5π -0.7071
Thus, we see that cosine function is exhibiting cyclicity at the interval of
The given x and y coordinates can be plotted on the graph to find the interval
