Question 675936
What is the Standard equation of the ellipse with the characteristics Center (4,4), vertical minor axis with length of 16 units, and c=6.
**
This is an ellipse with horizontal major axis since given minor axis is vertical.
Its standard form of equation: {{{y=(x-h)^2/a^2+(y-k)^2/b^2=1}}}, a>b, (h,k)=(x,y) coordinates of center.
For given ellipse:
center: (4,4)
given length of minor vertical axis=16=2b
b=8
b^2=64
given c of foci=6
c^2=36
c^2=a^2-b^2
a^2=c^2+b^2=36+64=100
Equation of given ellipse:
 {{{y=(x-4)^2/100+(y-4)^2/64=1}}}
