Notes
For each point on a flat floor, with its x and y, the equation gives a height z, so the graph becomes a landscape of hills, valleys and saddles. Colors show how high each part is.
Tap it and the surface lies flat, then rises out of the sheet and ripples, twists or breathes as a number called a changes. Pick one of 16 famous surfaces in the Splash tab, such as the sombrero, the saddle or Rosenbrock's banana valley, which is used to test computer methods that hunt for the lowest point. Or type your own: z = … with x and y, or with r and θ.
