how long is the major axis of the ellipse that is defined by the eqation given below?
(x-4)^2 over (9)^2 + (y+8)^2 over (11)^2 =1
..
(x-4)^2/9^2+(y+8)^2/(11)^2=1
This is an equation of an ellipse with vertical major axis of the standard form:
(x-h)^2/b^2+(y-k)^2/a^2=1, a>b, with (h,k) being the center of the ellipse.
For given equation:
a^2=11^2
a=11
length of vertical major axis=2a=22
