Math Is Fun Forum

Okay,my exams have ended,as n tends to infinity the bases will become infinitesimal,it can be proved using law of cosines.and as the n tends to infinity angle will become small and arc will become small,so both arc and base will become equal and it follows that area will be equal

Hi,if my calculations are correct then the inversion point is (129/65,47/65)
EDIT:the problem isn't as hard as i thaught,i am getting the line 4x+7y+13=0,is it correct?

If i can prove that property,i won't need eccentricity for the equation.
Here's a version of the statement for ellipse,the tangents to the end of minor axis lie on the intersections of circles containing ends of major axis and perpendinculars on foci.

Hi ozmark,
welcome to the forum.

Check this- http://www3.ul.ie/~rynnet/swconics/HP%27s.htm first property how was it derived???

Hi,binnoy
welcome to the forum
i disagree,this could be one of the purposes but not true one.

That's it,if i  check this thread again,i am going to lose the small brain i have!!!

This discussion is very confusing.....

I define a as the 1/2 of the distance of the two vertace and b as 1/2 of the line segment that is perpendicular to major axis,passes through center and its length corresponds to height of asymptotes over/under a vertex

Sorry for not being clear,c is distance of foci from center.if i assume a^2+b^2=c^2 i can derive the equation but how do i prove a^2+b^2=c^2?
[i tried searching in the net,all the websites i've been to say that proving it is tough and i should take it for granted]

Hey bob,I tried to derive the equation of hyperbola like this,I've got everything except a^2+b^2=c^2. How do i prove it?
