Concept explainers
Rotate the axes to eliminate the xy-term in the equation and write the equation in standard form. Sketch the graph of the resulting equation, shaming both sets of axes.
Answer to Problem 17E
The required equation in standard form is
Explanation of Solution
Given:
The equation of the conic
Rotation of axes to eliminate xy-term:
The general second-degree equation
By rotating the coordinate axes through an angle
The coefficients of the new equation are obtained by making the following substitutions
And
Consider the equation of the conic
The transformed equation is
Further simplify to find the value as shown below:
Thus the required equation in standard form is:
The graph of
