hello, would you please help me with this? Thanks in advance.
Consider the quadratic form given by Q(r, y) = 8r + 6xy.
1. Give the symmetric matrix associated with Q and find its eigenvalues.
2. Give unit vectors X, and X, which determine the axes of symmetry for the associated
curve CH : Q(r, y) = 0, and give the form of Q associated with these new coordinate
axes, that is, the form Q(u, v) = A1u² + A2v².
3. Classify CH (as an ellipse, hyperbola, empty curve, etc) and draw a sketch.
4. Give a formula for the locus of CH in terms of u and v.
