    Algebra (sort Of)

    Hi Everyone
    This is for my physics assignment but it is maths
    I have a formula n1sin1Ө=n2sin2Ө
    Where:
    n1 = 1
    n2 =?
    sin1Ө = 44
    sin2Ө = 48

    An my answer should be or close to 1.48. I can't get it.
    Help would be good.
    Thanks.

    Remember that the image of the function sin(x) is always between  [-1,1] so  sin (1\theta) and  sin (2\theta) can't be 44 and 48 !.

    That doesn't make sense

    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
    \sin 1\theta = 44 and \sin 2\theta = 48 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.

    Maybe my results are wrong, but even then I should get close to it because my results were quite good.
