Graph (x^2)/4+(y^2)/9=1
Problem
Solution
Identify the type of conic section. The equation is in the standard form of an ellipse centered at the origin
(0,0) which is(x^2)/(a^2)+(y^2)/(b^2)=1 or(x^2)/(b^2)+(y^2)/(a^2)=1 Determine the values of
a andb Since9>4 the ellipse is vertical. We havea^2=9 which meansa=3 andb^2=4 which meansb=2 Find the vertices and co-vertices. The vertices are located at
(0,±a) which are(0,3) and(0,−3) The co-vertices are located at(±b,0) which are(2,0) and(−2,0) Calculate the foci using the formula
c^2=a^2−b^2
The foci are located at
Sketch the graph by plotting the center
(0,0) the vertices, and the co-vertices, then drawing a smooth curve through the points to form the ellipse.
