Graphing Calculator 3D Parametric

Parametric Equations

Parametric equations allow defining x, y, z coordinates using u and v variables. It's a powerful feature that allows plotting complex graphs with 3 simple equations. With Graphing Calculator 3D you can plot parametric surface or line in 3D and set the desired range for u and v parameters.

In addition to cartesian coordinates you can also plot polar, cylindrical and spherical graphs using parametric equations.

Examples

  • Cartesian equations:
       x = u
       y = v^2
       z = sin(u+v)

  • Cartesian equations:
       θ = sin(u)
       φ = v
       r = cos(u+v)+v
