The Eccentricity of an Ellipse

[@richardfrederick1885]

For the last example I got a=5, b=3, c=4. Then e=c/a=4/5 and c=sqrt(a^2-b^2)=sqrt(25-9)=sqrt(16)=4. Everything fits.

Thank you very much :-D

What If a

[@linpehtulan5733]

then the oval's focus will be on y axis

[@Damianntuala]

not possible

[@Damianntuala]

@@linpehtulan5733 what if it initially it was on the y axis in other terms if a=b then its a circle but a cannot

[@7walkingman]

Then switch the names. What's important for eccentricity is that a is the larger one, not that it's associated with the x-axis.

I guess what I don't get is how come the two C values are different? I thought they were supposed to be the same

[@jaelsonnen5750]

Two seperate problems.

45/9 is wait.....very very great eh?!...wait....!...
lol!

[@nidhishgautam9043]

I guess went blank for that moment. common

[@jaelsonnen5750]

Lol I was laughing so hard at that, "and b squared is something.........veeeery, very guuud...five."

[@pradeepnepal7496]

How e= c/a

[@hassanamanatalijatt8442]

Nicely done in humour

[@IlicSorrentino]

Thank you very much

[@mussieg5807]

Well done ... but, u got minor mistake in your first example ... b=square root of 5

[@ThinkwellVids]

You're correct about b = square root of 5, but that's right in the video, too. Starting with c = square root of (a^2 - b^2). a^2 = 9. b^2 = 5. a^2 - b^2 = 9 - 5 = 4, and the square root of 4 is 2.

No mistake u are stupid

[@mrspumpkin6756]

Well explained to beginners
