Given:


((x-2)^2)/(36)+((y+3)^2)/(24)=1

Required:

Find the endpoints of the major axis and minor axis of the ellipse.

Step-by-step explanation:

The standard equation of the ellipse is:


((x-h)^2)/(a^2)+((y-k)^2)/(b^2)=1

Where h and k are the centers of the ellipse and a and b are the length of the axis.

Rewrite the given equation as:


((x-2)^2)/((6)^2)+((y+3)^2)/((2√(6))^2)=1

Compare the given equation with the standard equation we get


\begin{gathered} h=2,\text{ k=-3} \\ a=6,\text{ b=2}√(6) \end{gathered}

Since a>b so the coordinate x-axis will be a major axis and the y-axis will be a minor axis.

The coordinate of the major axis are:


(h\pm a,k)=(2\pm6,-3)

Take + sign


(2+6,-3)=(8,-3)

Take - sign


(2-6,-3)=(-4,-3_)

The coordinates of the minor axis are:


(h,k\pm b)=(2,-3\pm2√(6))

Take the + sign


(2,-3+2√(6))

Take the - sign


(2,-3-2√(6))

Final Answer:

The coordinates of the major axis are: (8,-3) and (-4,-3)

The coordinates of the minor axis are:


(2,-3\pm2√(6))
