Asked by Paula
what are the x-intercepts, and the y-intercepts and the foci of the ellipse
x^2/25 + y^2/36 = 1
x^2/25 + y^2/36 = 1

a = 5, b = 6,
the major axis is along the y-axis
so x-intercepts (5,0) (-5,0)
y-intercepts (0,6) (0.-6)

Notice that the denominators are perfect squares. So, either remember sqrts or just substitute in zeroes to get intercepts. Reiny did not give you the foci for some reason.
