Inequality Equations

The area a curve or the volume under a surface can be nicely rendered using semi-transparent colors that clearly demonstrate the extend of the area. This feature is especially powerful in 3D when the graph can be rotated in real-time to view the volume under a surface from all angles.

In addition to cartesian coordinates you can also generate the volume under the surface for polar, cylindrical and spherical equations.

Examples

  • Cartesian equations:
    • z < sin(x)+sin(y)
    • y < sqrt(z-x^2)
    • x > y^2
  • Spherical equations:
    • r < sin(θ+φ)^r
    • θ > φ+r
