Sampling Density
Sampling density is how many points per axis build the surface: more looks smoother but takes more browser work. It is fixed per page and shown in the status pill; narrow the x and y range for finer detail.
Graph z=f(x,y)
Type a formula, choose x and y ranges, then rotate the result to inspect slices.
Saddle vs Minimum
A saddle curves up in one direction and down in another, unlike a true minimum.
Surface and Contours
Contours are horizontal slices of the 3D graph projected into 2D.
