QUESTION:
Sketch the graph of the following ellipses. Plot and label the coordinates of the vertices and foci, and find the lengths of the major and minor axes. Use a graphing utility to check your work.
\(\frac{x^2}{9}+\frac{y^2}{4}=1\)
ANSWER:Solution 28E
Step 1:
In this problem we have to draw the graph of an ellipse +
=1, and we have to label the vertices, foci and the lengths of the major and minor axis.

Note ; We know that Standard form of an ellipse is ;
Center is ;(0,0) , vertices are ;( a, 0) ,(-a,0) , and foci is ( ae, 0) (-ae,0).
Length of the major axis is 2a , and the length of the minor axis is 2b.
