## The Vertex and Foci of a Parametrizied Conic ...

Hi Mapleprimes,

I have a conic section that is parametric.  Namely,

x(t) = 9t^2 + 3t  + 367
y(t) = 3t^2 + 2t + 122

How can I find the Vertex and Foci of this curve?
Also, How can I do this for the general case?

Regards,

Matt

Let a planar polygon P without selfintersections be given through the plottools:-polygon command.
How to find its triangulation as a set of triangles (The indication of common sides is desired too.) in an optimal way with Maple? This is used in the finite element method.

THis is part of the code I used in the geometry package:

with(geometry):

circle(c,50811.89143+x^2+y^2-61.91881776*x-446.5619114*y = 0);

line(l,1621.451347-0.1838809e-1*x-7.2593834*y = 0):

draw([c,l]);
intersection(X,c,l,[F1,F2]);

Hello

I've to do some geometric work ; the problem is that it seems to me there will be no other solution than trying a different approach of the problem, due to huge amount of time required by computation...

However, I would have liked to learn how my program can be fastened. I've heard of multi threaded programming model ; could it be applied here ?

To simplify, I have a initial point (its coordinates). My procedure...
