TriPlot 3D Graphing 2 [已付费版]

A simple app that draws 3D graphs. Supports 5 different forms of function:
- Standard surface (z = f(x, y))
- Spherical polar surface (r = f(θ, ϕ))
- Cylindrical polar surface (r = f(θ, z))
- Parametric surface (x, y, z = f(u, v))
- Parametric curve (x, y, z = f(t))
Features
- Graphs can be drawn as a smooth-shaded, lit surface or a wireframe.
- Displays up to 8 graphs simultaneously.
- Choice of perspective or orthographic view.
- Touch to rotate, pinch to zoom.
- Customizable colours for graphs and the graphing axis.
- Both trigonometric and hyperbolic trigonometric functions and their inverses are included.
- Graphs can be saved to a separate list for later use.
