Page "Cartesian coordinate system" Paragraph 20

The Coordinate system # Coordinate surface | coordinate surfaces of the Cartesian coordinates ( x, y, z ).

The z-axis is vertical and the x-axis is highlighted in green.

Thus, the red plane shows the points with x = 1, the blue plane shows the points with z = 1, and the yellow plane shows the points with y =− 1.

The three surfaces intersect at the point P ( shown as a black sphere ) with the Cartesian coordinates ( 1, − 1, 1 ).
