Find the vertices, foci, and eccentricity of the ellipse. Thank you.

x^2/16 + y^2/25 = 1

  • math - ,

    a^2 = 16 ---> a=4
    b^2 = 25 ---> b = 5

    major axis along the y-axis,
    vertices (4,0) , (-4,0) , (0,5) , (0, -5)

    c^ + 4^2 = 5^2
    c = ±3
    foci : (0,3) , (0, -3)

    e = c/b for an ellipse like that
    = 3/5
