Hello, I'd like to do the following manipulation. Let f be a homeomorphism (known explicitly). I want Mathematica to compute its inverse f^{-1} and to use it for further computations and plots. I'm assuming here that f^{-1} is not explicit (take f(x)=x+0.2Sin[x] for instance). I'm not sure that Mathematica has an already built-in function; do you know any simple algorithm? Many thanks
