Example text

A subcommittee formed for the task decided to name this the normal orientation. 7 were probably acceptable too, because they could be transformed to the normal orientation by placing a pin in the center of the page and rotating the map around the pin. 7, but no matter how fast they twirled them, they couldn’t seem to transform them to the normal orientation. It wasn’t until everybody important had given up and gone home that a tired intern, assigned to clean up the used coffee cups, noticed that the maps in the second row can be transformed into the normal orientation by holding them up against a light and viewing them from the back.

Still, many concepts in 2D do extend directly into 3D, and we frequently use 2D to establish an understanding of a problem and develop a solution, and then extend that solution into 3D. This section extends 2D Cartesian math into 3D. It is divided into four major subsections. 1 begins the extension of 2D into 3D by adding a third axis. 3. 2 describes how to specify the location of a point in the 3D plane using Cartesian (x, y, z) coordinates. 3 introduces the concepts of left-handed and right-handed 3D coordinate spaces.

Give the coordinates of the following points. Assume the standard 2D conventions. The darker grid lines represent one unit. Law of cosines 28 1. Cartesian Coordinate Systems 2. Give the coordinates of the following points: +y c a i g f e z b +x d h 3. ” Identify which of these combinations are left-handed, and which are right-handed. 4. In the popular modeling program 3DS Max, the default orientation of the axes is for +x to point right/east, +y to point forward/north, and +z to point up. (a) Is this a left- or right-handed coordinate space?
