Explain how to rotate axes to eliminate xy term for equation
Jose and Aparna were trying to rotate axes to eliminate xy term for equation x^2+2xy+3y^2-4x+5y-30. Jose used a=-pi/8 and Aparna a=3pi/8 used. Students got different equations in x' and y', but both were right. Describe how this is possible.
