Plotting a point is as simple as typing (2, 3, 4) . You can even label them or use variables to make them dynamic. 3. The Power of Variables and Sliders
Drag the slider to see your paraboloid stretch, flatten, and flip in real-time. 3d graph desmos
If you have multiple overlapping surfaces, click the gear icon to adjust the opacity. This helps you see "inside" spheres or through planes. Plotting a point is as simple as typing (2, 3, 4)
Enter the . Currently in its public beta phase, this tool brings the same intuitive "type and see" magic to the The Power of Variables and Sliders Drag the
) to draw a line or a spiral in space. For example, (cos(t), sin(t), t) will produce a 3D helix.
Just like in 2D, you can restrict a graph. For example, z = x^2 + y^2 {z < 4} will cut off your paraboloid at a height of 4. Why Use Desmos 3D?
One of Desmos's greatest strengths is its ability to handle implicit equations without breaking a sweat. Type x^2 + y^2 + z^2 = 25 to instantly generate a sphere with a radius of 5.
