More Trig help??? I Really need it!!?

My tutor told me that "π/3 on the unit circle is located at (1/2, √3/2). But when i say to take the SINE of π/3, that means you do opposite over hypotenuse, or in other words: y over r."

What does she mean? I am really confused. And i am afraid i am going to fail.....

    The value of sine is the y-coordinate. The value of cosine is the x-coordinate.
