# Where can I find good resources explaining conic sections?

I'm looking for something that explains them simply or something that has a lot of examples. The online course I'm taking doesn't explain them in much detail and I haven't managed to find something that explains it better. Mainly parabolas and hyperbolas. For parabolas, my course uses the formula $(x-h)^2 = 4p(y-k)$, so while I did find a useful video on KhanAcademy, on the subject, he uses a different formula and that just left me more confused.

• Apostol's Calculus has a very nice section on conics. – Pedro Tamaroff Aug 10 '13 at 0:23

I think the following book could be a good reference:

Calculus With Analytic Geometry by R.A.Silverman

Although it is an old one but it works yet. See the chapter $8$. You will see:

• Parabolas

• Ellipses and their equations
