To identify: the graph of the equation.
Answer to Problem 21E
The graph of the equation isparallel horizontal lines
Explanation of Solution
Given:
Calculation:
Given the following equation:
Comparing with the standard equation for a Quadratic Curve,
Thus,
For the cross-product term to vanish, the coordinate axes must be rotated by an angle alpha, suchthat
Therefore,
After rotation of coordinate axes, the original coordinates,
Substituting the above values of
Which are parallel horizontal lines.
Conclusion:
The graph of the equation isparallel horizontal lines
