DISCONTINUITIES IN A CURVE



Hi all,

Bernard Luce was having some trouble posting a question to the list. I'm
including the contents here.

DISCONTINUITIES IN A CURVE

A parametric curve displays 2 cases of discontinuity in the interval
chosen (t= 1 and t = - 2) (see command below). However the infinite
branches are unexpectedly linked. So, two questions :

1? is there any option to draw properly the curve and display the
   discontinuities ?

2? Might you provide the main commands in the ASYMPA package to compute
   the asymptotes and draw them together with the graph as well ?

THANKS BEFOREHAND
