Given the equation of a conic section, how can I:(adsbygoogle = window.adsbygoogle || []).push({});

1) find its focii

2) find the equations of its directrices

3) find out what type of conic it is, without using either the arduous matrix method or the equally arduous rotation method

To be honest, I don't really like conic sections and I'm just looking for an algorithm for these.

Thanks for any help.
