Answer:
See below.
Explanation:
We are given the displacement as a function of time as,
If we are given a sum of functions which have different periods, we divide the LCM of the periods with the HCF of the periods.
We take T = 1 s and t = 1 s. Therefore, omega ( angular frequency ) is 2 pi.
The period of,
For the time period of x{ t ],
Which gives,
Which is evident from the graph too. See the attached graph. The blue line is sin( x ) and the red line is the displacement function. Both have a period of 2 pi.
