I have a discreet set of {x,y} points and I want to check if each is in a particular continuos set of {x,y} points. I can only define the region parametrically but other then that it looks something like this region= {-1<x<1 , 0<y<2} I want to perform a test like {x,y} "included in" region {0,1} "included in" region ->True {5,7} "included in" region ->False Is this possible My region is defined in a more difficult manner. It looks more like this region = F[{theta,fi}] for {-pi/2 < theta < pi/2}, {-pi < fi < pi } where F returns an {x,y} pair -NAUM
