We're covering conic sections, so far it's just circles ellipses and hyperbolas. I have one question regarding graphs, and two regarding Hyperbolas. I don't have any clue where to start with these, so even just telling me the basic formula would be much obliged.
Graph the following inequality. X^2-6y^2<36
I know for this one you just start off diving by 36, getting X squared over 36, and Y squared over 6, but after that I'm lost on how you graph it.
Give the vertices, foci, and equations of asymptotes for the hyperbola Y^2/16- X^2/81=1
Find an equation of the hyperbola with foci (0 +/-6) and with a difference of focal radii of 8.
The last two Im totally stumped on.
