Find when x and y are connected by the relation given
(x² + y²)² = xy

We have,

(x² + y²)² = xy

By product rule:

Find when x and y are connected by the relation given

sec (x + y) = xy

Find when x and y are connected by the relation given

tan^-1 (x² + y²) = a

If ax² + 2hxy + by² + 2gx + 2fy + c = 0, then show that

If prove that
