Ineed with all of these. i am in online school so i don't have a teacher to explain this to me and am struggling.
1.)what is the directrix of the parabola given by the equation r= 2/1+sinθ ?
rsinθ = 2
sinθ = 2
rcosθ = 2
r = 2
2.) choose the equation of the conic section described. a parabola with focus at the pole and directrix rsinθ = - 5
3.)choose the equation of the conic section described.
focus at the pole, eccentricity of 2/3, vertical directrix 2 units to the left of the pole
4.)write the equation of the conic section satisfying the given conditions.
focus at the pole, e = 3/4, horizontal directrix 2 units above the pole
5.)the equation of a parabola is r= 6/1+cosθ. the vertex of the parabola is located at
(3, 0°)
(6, 0°)
(3, 180°)
(6, 180°)
