b = 5 a = ?
ganeshie8
  • ganeshie8
if u can find a, u can write the equation of ellipse :- \(\large \frac{x^2}{a^2} + \frac{y^2}{b^2} = 1\)
ganeshie8
  • ganeshie8
any idea how to find "a" ? :)
anonymous
  • anonymous
How do I find a? Is there a formula I have to follow?

u just need to knw how to find an unknown side in a right triangle
anonymous
  • anonymous
Use the pythagorean theorem.

a^2 = b^2 + c^2 a^2 = 5^2 + 3^2

simplify

a^2=34
ganeshie8
  • ganeshie8
yes, you want "a" right ?
anonymous
  • anonymous
Yes. So do I divide 34 by 2?
ganeshie8
  • ganeshie8
noo, you need to take "square ROOT" both sides
anonymous
  • anonymous
So \[a=\sqrt{34}\]

  • ganeshie8
actually im wrong, a^2 is enough as u put it earlier,,,, i see we dont need to find a -.-
ganeshie8
  • ganeshie8
directly plugin a^2 value in the equation
ganeshie8
  • ganeshie8
\(\large \frac{x^2}{34} + \frac{y^2}{25} = 1\)

^^final equation of ellipse
anonymous
  • anonymous
Whoaaa that confused me. So that's the final equation, is the work we did before still correct? Well except the finding a parts?
ganeshie8
  • ganeshie8
everything is correct, you could even find "a", and plugin the "a" value back into the equaiton
ganeshie8
  • ganeshie8
but thats just extra unnecessary work
ganeshie8
  • ganeshie8
when u knw that u will be needing oly "a^2", why to find "a" ?
ganeshie8
  • ganeshie8
it wont be a mistake to find "a", its just pain to take square root of 34 lol.. .hope u get me :)
anonymous
  • anonymous
I wasn't too sure how to do this at first so I just went with ya lol. I get it though. Thanks for your help :)
ganeshie8
  • ganeshie8
np :) u wlc :))
