The periodicity of function is
<em><u>Solution:</u></em>
Given that we have to find the period of function
<em><u>Given function is:</u></em>
<em><u>Use the below formula:</u></em>
Thus,
Now find the periodicity of cos(x)
We know that,
periodicity of cos(x) =
Therefore,
Thus the periodicity of function is
