For three-dimensional space, in general you need three components. You may need three components for forces, for positions, for velocities, etc.
(x,y,z)
The answer is -2
Three coordinates suffice to define a location in space. On a surface only two coordinates are required.
With coordinates. A reference frame is chosen (a point of origin, and directions), and the position is described with two or three numbers (one for each dimension required), in relation to the point of origin.
When applied to radiosurgery, stereotactic refers to a system of three-dimensional coordinates for locating the target site
Presumably, the "three dimensional triangular plane" is actually a two dimensional plane which is "tilted" with respect to the axes. The point of intersection is simply the coordinates of the solution to the simultaneous equations for the line and the plane.
' -6 ' and ' 6 ' are not points. On a 2-dimensional (flat) graph, you need two coordinates to locate one point. (On a 3-dimensional (solid) graph, you need three coordinates to locate one point. And there's no such thing as a 1-dimensional graph.)
There are only three coordinates. This indicates three points in 1-dimensional space (in which case there is no slope) or one point in 3-dimensional space (in which case there is no specific line).
Points with integer coordinates are often called lattice points. Lattices exist in all dimensions.When we talk about lattices points on the rectangular Cartesian coordinate system, this is a two dimensional lattice. Three dimensional lattice points are often used to study crystals.
You can locate a point by associating it to coordinates, either in a two dimension plan, x, y, or three dimensional, x, y, z.
