What Geometric properties of Conics do we need to know?

 

[Carrotsticks]

Reflection property, PS=ePM, PS + PS' = 2a.

Reflection property, PS=ePM, PS + PS' = 2a.

Thanks!

BTW equivalent expressions for the hyperbola are also required.

Is there a reflective property for hyperbola and a PS + PS' sort of thing?

Yep, there are. The reflective property of the hyperbola was touched on last year.

And the one of the hyperbola is |PS - PS'| = 2a

I see, nothing special we need to know about parabola though right?

Can't think of anything other than e=1.

Can't think of anything other than e=1.

And the reflective property.

And the reflective property.

Yep cheers, definitely the reflective property, but I feel that is moreso 3U than 4U.

However, please feel free to correct me.
