The question asks for a probability density function, and says it is defined between 0 and pi/3.
Since its a p.d.f the area under the graph must equal to 1.
If you integrate 2sin(x) with your limits as 0 and pi/3 you get 1, though how you are able to work out 2sin(x) without being told I am not sure, and I would have interpreted "uniformly distributed" as the p.d.f being in the form f(x) = k
