Question 1120795
-------------------------------------------------------------
What is the length of the minor axis of the ellipse whose equation is x squared plus 4 y squared equals 64 space ?
----------------------------------------------------------
??


{{{x^2+4y^2=64}}}

-

{{{x^2/64+y^2/16=1}}}


{{{x^2/(8^2)+y^2/(4^2)=1}}}

.

Compare to  {{{x^2/a^2+y^2/b^2=1}}}, in which b is semi-minor axis.


length of semi-minor axis,  4.
Length of entire minor axis, 8.
