Best ResponseYou've already chosen the best response.3if u can find a, u can write the equation of ellipse : \(\large \frac{x^2}{a^2} + \frac{y^2}{b^2} = 1\)

Best ResponseYou've already chosen the best response.3actually im wrong, a^2 is enough as u put it earlier,,,, i see we dont need to find a .

Best ResponseYou've already chosen the best response.0Whoaaa that confused me. So that's the final equation, is the work we did before still correct? Well except the finding a parts?

Best ResponseYou've already chosen the best response.3everything is correct, you could even find "a", and plugin the "a" value back into the equaiton

Best ResponseYou've already chosen the best response.3when u knw that u will be needing oly "a^2", why to find "a" ?

Best ResponseYou've already chosen the best response.3it wont be a mistake to find "a", its just pain to take square root of 34 lol.. .hope u get me :)
