Answer:
x<3
The circle isnt full so dont underline the <
x = A cos ω t
where,
A is the amplitude
ω is the angular frequency
Since the shape is a circle, therefore the amplitude is
simply equal to 2π or 6.28 rad while the angular frequency is 5 rad/s, therefore:
x = 2π cos 5 t
Check the picture below
the angle is in degrees, thus, make sure your calculator is in Degree mode
