The range of the sine function is [-1, 1]; meaning, when you take the sine of any angle it's going to be a number between -1 and 1, so to say that and is impossible. Can you double-check the assignment and see how exactly the problem is worded?
Oh, maybe I've just made a mistake with the image word, in spanish range and image (rango e imagen) are equivalent, so maybe I just didn't make my point clearly. In that case, my apologies.
