Homework Statement
Find the equation for a hyperbola centered at the origin with points (-10,3pi/2) and (2,pi/2)
Homework Equations
x^2/a^2 -y^2/b^2=1 or y^2/a^2 - x^2/b^2 = 1
* r=ke/(1±ecos(theta))
*cos can be replaced with sin and the ± is either a plus or a minus depending on the directrix
The Attempt at a Solution
I think the second equation is the only one that can be used but I do not know how to solve with that equation without guessing and checking.
Using the first equation I attempted to plug in values for x and y (they did not check out) in the first equation but I am pretty sure that the coordinates are polar coordinates. I am not really sure what to do but if you could point me in the right direction that would be great. Sorry I do not have the original problem so I do not know the question word for word. Any help would be much appreciated.
