Sestrojení elipsy (help)


Recommended Posts

Čus. Na deskriptivní geometrii sme dostali za úkol narýsovat elipsu a hyperbolu, ale vůbec netušim jak udělat tu elipsu, a tak za každou radu bych byl vděčný.


Do jednoho obrázku sestrojte elipsu a hyperbolu, které mají ohniska ve stejných bodech:

Elipsa je dána: a= 6cm, e= 4cm

Hyperbola je dána: a=2cm, e=4cm

(a=Střed elpisy->A/B | e=Střed elipsy->E/F)

A/B=bod elipsy, který leží na ose x

E/F=ohnisko elipsy
