The frequency is 1/1080 and the value of b is 1/3
How to determine the values of frequency and b?
The period is given as;
T = 1080
The frequency is calculated using:
f = 1/T
So, we have:
f = 1/1080
The value of b is calculated using:
2π/b = T
This gives
2π/b = 1080
Make b the subject
b = 2π/1080
Express 2π as degrees
b = 360/1080
Divide
b = 1/3
Hence, the frequency is 1/1080 and the value of b is 1/3
