WT41: Conics via projective geometry

[sorrysonofa]

this is great stuff, I am currently learning some projective geometry in my spare time, and this visualisation helps!

Just beautiful.

Do we have YouTube access in the exam?

For linux junkies such as myself there's a FOSS alternative to Geometer's Sketchpad called "kig", part of the KDEEdu package. Unfortunately, it is vastly inferior, and can only draw locuses (loci?) of points so you'll only be able to see the point-conic. Unless you sit there for hours manually drawing in lines for the line-conic.

Hi Simon,

Thanks for that info. There are also some other variants, called Cabri and another called Cinderella.
