    How do I solve "sin x = .948"?

    I know that it involves an arc(trig function) but I don't exactly know which. I'm having a (very) rough year in trigonometry but was hoping someone could teach me how to solve that basic problem.

    To undo a sine, try using the arc-sine.

    Thank you very much =)

    So would the equation I use to solve look like this:

    x = arcsin .9486

    Yep, since sin(x) repeats itself the answer would be x = arcsin(.9486) \pm 2k\pi where k is an integer and radians are used
