In order to better understand why your world is three dimensional, consider zero, one and two dimensions.

This lesson demonstrates how three-dimensional objects can be drawn in a three-dimensional space. It is 2 of 5 in the series titled "Drawing Three Dimensional Objects."

This MathWorld page discusses Cartesian coordinates and the Cartesian coordinate system. Includes somewhat advanced and complicated information!

Use this calculator to calculate the distance between 2 points by entering 2 sets of coordinates in the 3-dimensional Cartesian coordinate system, (X1, Y1, Z1) and (X2, Y2, Z2), to get the distance formula calculation for the 2 points...

The purpose of this lesson is to teach students about the three dimensional Cartesian coordinate system. It is important for structural engineers to be confident graphing in 3D in order to be able to describe locations in space to fellow...

Use this calculator to calculate the distance between 2 points by entering 2 sets of coordinates in the 3-dimensional Cartesian coordinate system, (X1, Y1, Z1) and (X2, Y2, Z2), to get the distance formula calculation for the 2 points...

This question examines the algebraic equations for three different spheres. The intersections of each pair of spheres are then studied, both using the equations and thinking about the geometry of the spheres. Aligns with A-CED.A.2 and...

Advanced discussion of the components of a vector on a three dimensional plane is available here along with formulas and properties.

In Spanish. You can study interactively in this unit lines and planes in space, their equations and their relative positions.

In Spanish. This unit extends the model of Cartesian representation to three dimensional. You will be able to study interactively some curves and surfaces in space, its parametric and implicit equations.

Based off of the hit television show NUMB3RS, this diverse lesson has students perform linear regression analysis (to compare two fire variables), check three-dimensional points using a planar equation, and evaluate points to determine...

A site featuring the work of Cezanne, Monet, Picasso, and Mondrian, among others, that explores pictorial space in a composition There are lesson plans for ages 4-18, and a great section where works are juxtaposed for comparison. Use the...
