We call this system the three-dimensional rectangular coordinate system. It represents the three dimensions we encounter in real life. The three-dimensional rectangular coordinate system consists of three perpendicular axes: the x -axis, the y -axis, and the z -axis.

We extend vector concepts to 3-dimensional space. This section includes adding 3-D vectors, and finding dot and cross products of 3-D vectors. Skip to main content

Sep 17, 2022 · We start with the basics of drawing a vector in 3D. Instead of having just the traditional \(x\) and \(y\) axes, we now add a third axis, the \(z\) axis. Without any additional vectors, a generic 3D coordinate system can be seen in Figure \(\PageIndex{1}\).

The Vector Calculator (3D) computes vector functions (e.g.

3D and Contour Grapher. A graph in 3 dimensions is written in general: z = f(x, y). That is, the z-value is found by substituting in both an x-value and a y-value. The first example we see below is the graph of z = sin(x) + sin(y). It's a function of x and y.
