1. The problem statement, all variables and given/known data
The function f with domain 0\leqx\leq180
is defined by f(x)=2sinx/Sketch and find the range of f.

2. Relevant equations

well..i havent got a clue, if i try to get value for 2sin(0) gives me zero and for 2sin(180) gives me the same answer =/.Thanks in advance.

If you sketch the graph of y = 2 sin(x), you should be able to see at a glance the range of this function. Your x values are in degrees, which you should state.

Do you know what the graph of y = sin(x) looks like? The graph of your function is related to this one.

So try numbers between 0 and 180!
