by solving above  equation
so the partical can travel from -2to+2 on x axis
so range is [-2,+2]

Dear Vidhya,
Given, x=(root 3 )sin omega t- cos omega t
In trigonometry we knw that,
maximum of {a sin theta + b cos theta}=root over{a2+b2}
minimum of {a sin theta + b cos theta}= – root over{a2+b2}
Similarly in your question,
maximum value of x=root over{ (root 3)2-(1)2 };
minimum value of x= – root over{(root 3)2+(1)2};
So, x lies between -2 and +2.
Region in which particle is confined = [ - 2 , + 2 ]
Approve if my answer helped you and in case any doubts put it in the comment box.
