z = f(x, y) · drag to orbit

Controls

z = f(x, y)

▶ Run in Python

Data Inspector

Grid34×34

Variablesx, y

Governing equation

z = f (x, y) = sin(sqrt(x*x+y*y))

Reading this result: This surface is radially symmetric: it depends only on distance from the origin, so it looks the same from every direction around the vertical axis.
