## Solving z=w/2−sin(tw)/(2t)z=w/2-\sin(tw)/(2t) for ww

Is it possible to solve z=w2−sin(tw)2t, for w? My first thoughts were that we would have to be careful about the domain of f(w) so that the inverse was actually a function (and not a multi-valued function). But, on graphing f(w) for various values of t, e.g. t=1 below, I think the domain can actually … Read more
