Figure 21: Elliptical quadratic minimum

Equation: z = 0.08*x^2+0.18*y^2
Domain: x in [-5.0, 5.0]; y in [-5.0, 5.0]
Variables: dimensionless
Angle mode: radians
Camera: {'yaw': -48, 'elevation': 36, 'distance': 4.8}
Display: Native independent normalization: x/y -> [-1,1], z -> [-0.8,0.8]. Relative z/x exaggeration = 0.8*x_span/z_span. No vertex edits.
Sampled z range: [0, 6.5]
Mesh side: 129

Sampled mesh extrema may differ from exact function extrema; no coordinate labels are projected onto the image.

Caption: The origin is the unique global minimum: f(0,0)=0. Unequal positive curvature creates an elliptical bowl.

Alt text: Blue and orange elliptical quadratic bowl on black, shown in perspective with independently normalized axes.
