Graph (x^2)/16+(y^2)/6=1
Problem
Solution
Identify the type of conic section. Since the equation is in the form
(x^2)/(a^2)+(y^2)/(b^2)=1 with positive denominators, it is an ellipse centered at the origin(0,0) Determine the lengths of the semi-axes. Here,
a^2=16 andb^2=6 Taking the square roots givesa=4 andb=√(,6)≈2.45 Locate the vertices on the major axis. Since
a^2>b^2 the major axis is horizontal. The vertices are located at(±a,0) which are(4,0) and(−4,0) Locate the co-vertices on the minor axis. The co-vertices are located at
(0,±b) which are(0,√(,6)) and(0,−√(,6)) Calculate the foci using the relation
c^2=a^2−b^2 Substituting the values givesc^2=16−6=10 soc=√(,10)≈3.16 The foci are at(±√(,10),0) Sketch the graph by plotting the center, vertices, and co-vertices, then drawing a smooth curve to connect them into an oval shape.
