Write an eqaution in standard form for the eplipse
with foci of 6,0 and -6,0
an vertices of 3 and -3
could somone show me step by step how to do this i can get half the equation then the rest comes out mest up

Well, if the foci are (-6,0) and (6,0), then the ellipse is centered at the origin (0,0). The general form of an ellipse is:
((x-h)^2)/a^2 + ((y-k)^2)/b^2 = 1
note: sorry for the crappy notation, but (x-h)^2 means (x-h) squared, just in case you didn’t understand
the center of an ellipse is (h,k). since the center is (0,0), you really have:
x^2/a^2 + y^2/b^2 = 1
The length of the horizontal axis is 2a, which is from -6 to 6 for a total distance of 12. So a=6. The length of the vertical axis is 2b, which is from -3 to 3 for a total distance of 6. So b=3.
This now gives you the equation:
x^2/36 + y^2/9 = 1
So there ya go. That should be right. I’m dead tired, just put in a 12 hour day, and am drowsy from NyQuil, so I apologize if there’s errors. Hope that helps!

i’d totally be into it if i could understand it. at ecc i had to take elementary algebra that didn’t even count as a credit because i’m so bad in math. i couldn’t imagine taking calc. i should buy some math books or something. hahaha.

to an extent, but its like taking a pre-alg before you take algebra. calc is more or less this

calc is basically a change in something over a change in another measurement, hence the deltax/deltay
