You need to push the parabola down or flip it so that the x-axis becomes to the latus rectum. eg. x²=-4a(y-a) Put that in terms of y and integrate between -2a and 2a. EDIT: Or err.. Just integrate y = x²/4a between -2a and 2a. Then subtract that from the rectangle of 4a*a >_<

Mine's in bad condition :(

Would it be possible for you to learn how to derive the formulas? eg. rθ comes from (θ/2π)2πr

Lies, they're great for tiny bills. I've heard they have terrible customer services, but I haven't had to call them in 3 years. I'd like to see any company beating this for value; ADSL2+, 12GB/40GB. This is including all phone calls made as well as phone line rental!
