Thread: Can someone explain how I do this one?

Find a polar equation of the conic with focus at the pole and the given eccentricity and directrix.
e=3/2,ysinΘ=1

There is a rule for eccentricity. e > 1 tells you it is what sort of conic? Hint: You're going to need another focus and directrix.

Conics look like this in polar coordinates: parallel to the polar axis, or

perpendicular to the polar axis.

You have e = 3/2 -- Alarm goes off! This is a hyperbola.

If you mean , then we have a horizontal line. (Pretty obvious that this tranlsates to y = 1?). Okay, what form is that?

We are so close...

Note: Is that enough information for uniqueness?
