How do I do question 7b (i) on the 05 paper? How is H=2sinx ?
2. 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
