This graphing calculator is user friendly and powerful. 
It is fully compatible with iOS 14 and 15, and mostly compatible with iOS 13 and Mac OS.

Cartesian 3D Z = F (X, Y) functions: 
———————————————————
Graphs can be: 
1. Drawn as surface, lines, or dots.
2. Drawn with or without perspective, and with different light and reflection settings.
3. Tilted up or down.
4. Rotated to any position.
5. Drawing is animated by either X, Y, or Z.

Table of all points can be sorted by either X or Y.

Cylindrical 3D Z = F (Θ, R) functions: 
———————————————————

2. Drawn with or without perspective, and with different light and reflection settings.
3. Tilted up or down.
4. Rotated to any position.
5. Drawing is animated by Θ, R, or Z.

Table of all points can be sorted by either Θ or R.

Cartesian 2D Y = F (X) functions: 
————————————————
Graph displays the following curves:
1. One or two Y = F (X) functions.
2. Derivative of the first function.
3. Integral of the first function as a shade and a curve. 

Graph features: 
1. Drawing is animated by X.
2. Clicking on the curves shows curve values, and finds closest point in the table.

Tables:
1.  All function, integral, and derivative values.
2.  Zero intersections of first function.
3.  Intersections between first and second functions.

Polar 2D R = F (Θ) functions:
