What are Parametric Equations?
Before diving into how to plot parametrics in Desmos 3D, it's essential to understand what parametric equations are. Unlike traditional functions that express a dependent variable in terms of an independent variable, parametric equations represent a set of equations where both the x and y coordinates are defined by one or more parameters. This allows for more flexibility in representing curves and surfaces in a multi-dimensional space.
How Do Parametric Equations Work?
Parametric equations typically take the form:
- x = f(t)
- y = g(t)
- z = h(t) (for 3D plots)
Here, 't' is the parameter that varies over a specific interval, resulting in a set of coordinates (x, y, z) that define a curve or surface in space. By manipulating the equations and the parameter, you can create a wide variety of shapes, from simple lines to intricate spirals and surfaces.

How to Plot Parametrics in Desmos 3D: A Step-by-Step Guide
Now that you have a basic understanding of parametric equations and the benefits of using Desmos 3D, let’s dive into the practical steps of plotting them.
Step 1: Accessing Desmos 3D
First, navigate to the Desmos website and select the 3D graphing calculator. You can find it by searching for "Desmos 3D" or directly accessing the calculator through the Desmos homepage.
Step 2: Inputting Parametric Equations
Once you are in the 3D graphing environment, you can input your parametric equations. Here’s how:
- Click on the "+" button to add a new expression.
- Input your parametric equations in the following format:
- For example:
x = cos(t),y = sin(t),z = t - Specify the range for the parameter
t, such ast = 0 to 2π.
Step 3: Adjusting the View
After inputting your equations, you may need to adjust the viewing angle to better visualize the plot. Use your mouse or trackpad to rotate the graph and zoom in or out as needed. This will help you see the full extent of the parametric plot you have created.
Step 4: Exploring and Modifying Parameters
Desmos allows you to modify parameters dynamically. You can create sliders for your parameters to see how changes affect the graph. To create a slider:
- Click on the "+" sign next to your parameter, such as
t. - Select "Add Slider".
- Adjust the slider range to see how the graph evolves.
What Are Some Examples of Parametric Equations You Can Plot?
There are numerous fascinating parametric equations that you can explore in Desmos 3D. Here are a few popular examples:
- Spiral:
x = t * cos(t),y = t * sin(t),z = t - Helix:
x = cos(t),y = sin(t),z = t - Paraboloid:
x = u * cos(v),y = u * sin(v),z = u^2
