15-28 ■Graphing a Rotated Conic (a) Use the discriminant to determine whether the graph of the equation is a parabola, an ellipse, or a hyperbola. (b) Use a rotation of axes to eliminate the xy-term. (c) Sketch the graph.

21 x 2 + 10 3 x y + 31 y 2 = 144

To determine

a)

Whether the graph of the equation is a parabola, an ellipse, or a hyperbola by the use of discriminant.

Explanation

Given:

The equation is 21x2+103xy+31y2=144.

Approach:

The graph of the general equation Ax2+Bxy+Cy2+Dx+Ey+F=0 is either a conic or a degenerate conic. In the non degenerate cases, the graph is

1. If B24AC=0, then the graph is a parabola.

2. If B24AC<0, then the graph is an ellipse.

3. If B24AC>0, then the graph is a hyperbola.

Here, the B24AC is the discriminant.

Calculation:

The equation is

21x2+103xy+31y2=14421x2+103xy+31y2144=0

On comparing the general equation,

A=21,B=103,C=

To determine

b)

The equation without xy-term by the use of rotation of axes.

To determine

c)

To sketch:

The graph of the equation 21x2+103xy+31y2=144.
