2021年3月5日 · Solve for x, y x, y : x4 +y4 + 2 = 4xy x 4 + y 4 + 2 = 4 x y. Obviously, the very obvious solutions are (1, 1) (1, 1) and (−1, −1) (− 1, − 1). But I don't know how to reach the answer. I got the answer through hit and trial. I tried adding and subtracting 2x2y2 2 …

2019年4月16日 · $z=4xy$ is the same as $z=(x+y)^2-(x-y)^2$, so after the (linear) change of variables $x'=x+y$, $y'=x-y$, you get $x'^2-y'^2=z$, which has the form of a hyperbolic paraboloid. In other words, the surface $z=4xy$ is the image of the hyperbolic paraboloid $x^2-y^2=z$ after applying a linear transformation to it.
