conique takes as argument the equation of a conic with
respect to x,y. You may also specify the names of the variables as
second and third arguments or as a vector as second argument.

conique draws this conic.

Input :

conique(2*x

`^`

2+2*x*y+2*y`^`

2+6*x)Output :

the graph of the ellipsis of center -2+i and equation 2*x

`^`

2+2*x*y+2*y`^`

2+6*x=0
Remark :

See also conique_reduite for the parametric equation of the conic.
