Question

what is the equation of an ellipse

Answer 1

(x/a)^2 + (y/b)^2 = r^2

Answer 2

thanks so much

Answer 3

General form of ellipse: ax^2 + by^2 + cx + dy + e = 0.
Another form is:
\[\frac{ (x-h)^2 }{ a } + \frac{ (y-k)^2 }{ b } = 1\]

Answer 4

\[\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1\]

Answer 5

Center is (h,k)
Length of major axis is 2a
Length of minor axis is 2b

Answer 6

thanks to all for all your help

Answer 7

o i forgot the points (-4,7) (-1,2) (-4,3) (-7,2) can you guys help me figure out how to plug in these points into this formula

Answer 8

x^2/a^2 + y^2/b^2 = 1

Answer 9

thats it really?
