What is the coX of {(x,y) $\in$ $\mathbb R^2$ : y = $1\over1+x$, $x \ge 0$ } ?

coX is the convex hull.

I couldn't figure out. coX should be the smallest convex set that contains the set but in this case should it be the hyperbola itself. Thanks for helping.

    Line?? It is a *hyperbole*. Which line were you thinking about?2012-11-01

    @Berci yeah it is a hyperbole.2012-11-01

    But it is not convex.2012-11-01

    @Berci that is the whole point we are trying to find, create a convex hull for this set.2012-11-01

    Technically that's a *hyperbola* in English. "Hyperbole" is a non-scientific word that means "exaggeration".2012-11-01
