I have some problems to work and I cannot find anything through searching, I can make up a problem, but for example

find sin3x if sinx=1/3 and 0 < or equal to sin greater than or equal to pie/2

How would I find x? I now how to plug in a radian into my calculator to get the answer the opposite way but not this way.
