Calc 3D can do statistics, best fits, function plotting, integration. It handles vectors, matrices, complex numbers, quaternions, coordinates, regular polygons and intersections. Calc 3D is advantageous, because it solves mathematical problems in a very direct way. For example: What is the intesection of 2 line? Calc 3D answer: The 2 lines intersect at the point ... Or if they are parallel, Calc 3D tells you. There are different ways to define lines (parameter form or point form). Calc 3D knows and converts them.

Calc 3D is a collection of mathematical tools for highschool and university. The calculator can do statistics, best fits, function plotting, integration. It handles vectors, matrices, complex numbers, coordinates, regular polygons and intersections. For objects ( like point, line, plane and sphere) distances and intersections are calculated. Cartesian, spherical and cylindrical coordinates can be transformed into each other. Carthesian plot, polar plot, parametric plot, best fit, fast fourier transformation, histogram, smooth,..

Two version from Calc 3D:
1. The standard version combinates in 3 dimensions: point, line, plane, sphere. For example: If you have a line and a plane, Calc 3D gives the point of intersection or distance.
2. The professional version combinates in 3 dimensions: point, line, plane, sphere, line between 2 points, triangle, quadrilateral and in 2 dimensions: point, line, circle, line between 2 points, triangle, quadrilateral

Calc 3D Pro Features:
1. Intersections: Calc 3D is advantageous, because it solves mathematical problems in a very direct way. For example, what is the intesection of 2 line? Calc 3D answer: The 2 lines intersect at the point ... Or if they are parallel, Calc 3D tells you.
2. There are different ways to define lines (parameter form or point form). Calc 3D knows and converts them.
3. The standard version combinates in 3 dimensions: point, line, plane, sphere. For example: If you have a line and a plane, Calc 3D gives the point of intersection or distance.
4. The professional version combinates in 3 dimensions: point, line, plane, sphere, line between 2 points, triangle, quadrilateral and in 2 dimensions: point, line, circle, line between 2 points, triangle, quadrilateral
5. Complex, quaternions: Complex numbers, when you change the real or imaginary part, the magnitude and phase angle change automatically, and vice versa. To multiply 2 complex numbers by hand, you need to multiply 4 real numbers and add the results. Calc 3D does it in one click. Before Calc 3D, teachers had to work hard at the board, and pupils were mostly confused.
6. The professional version has also a graphical output.
7. Vectors: For vectors basic operations, crossproduct, spar product, unit vector and angle between two vectors can be evaluated.
8. The professional version has more dimensions and a random generator.
9. Matrices: For matrices basic operations, inverse, determinante, rotation matrix and multiplication with a vector can be evaluated.
10. The professional version can also split in 2 diagonal matrices, sum the diagonal elements, transpose the matrix, has more dimensions and a random generator.
11. Coordinates: Here you can transform cartesian, spherical and cylindrical coordinates into each other.
12. Languages: german, english, spanish, italian, portuguese
13. Plotting functions: no 2D, polar, 3D, Contour
14. Editor: load, save, print, printerpreview, font, table, paragraph, color
