Show, using algebra, that the formula for a parabola is a special case of the formula for an ellipse. I have no problems even paying 5$ after the answer has been received via paypal.... seriously...
where c is the distance from the center to the focus of the ellipse a is the distance from the center to a vertex
if that is what you are asking
hmm, very interesting fact. The fun part will be to write an equation that makes sense.
This helps me start in a direction, i had no clue prior to this and my professor is not helpful at all
ok well i might not be very good at explaining this but i found a website that can, i hope this leads you in the right direction, here is the link. http://www.sophia.org/finding-the-equation-for-an-ellipse-concept?topic=conic-sections-circles-and-ellipses
