Question

Write a polar equation in r and θ of a conic
with the focus at the origin, and eccentricity
7/8
and directrix y = 2.

Answer 1

how is eccentricy defined?

Answer 2

idk??................

Answer 3

that might be something you would want to look up then, conics can be identified by their eccentricity, but i cant remember how it is defined.

Answer 4

greater than 1=parabola
less than 1 but greater than 0 =ellipse
less than 0=hyperbola

Answer 5

so this would be an ellipse right?

Answer 6

i think that 7/8 is related to b/a

Answer 7

c/a ... i was close :)
