Abstract

A method for relating at least two mathematical objects in a computing apparatus having a graphical user interface is described. The method comprises receiving instructions via the graphical user interface to relate a first mathematical object with a second mathematical object; updating the second mathematical object using data of the first mathematical object; linking the first mathematical object to the second mathematical object; and creating a visual link between the first mathematical object and the second mathematical object.

4. The method of claim 2, wherein said visual link is indirectly linked to said at least one mathematical object via at least one other mathematical object.

5. The method of claim 1, wherein said visual link is hidden when no mathematical object associated thereto is selected.

6. The method of claim 1, wherein said visual link comprises a link removal button.

7. The method of claim 6 farther comprising:

detecting clicking on said link removal button;

identifying said visual link that said link removal button is associated thereto;

identifying said at least two mathematical objects that said visual link associated thereto;

deleting said visual link; and

deleting said link between said at least two mathematical objects.

8. The method of claim 7 further comprising:

highlighting at least one of said first and second mathematical objects.

9. The method of claim 7, wherein said mathematical objects comprise at least one of table objects, graph objects, equation objects and shape objects.

10. The method of claim 1 further comprising:

detecting changing of said first mathematical object; and

updating said second mathematical object using data of said first mathematical object.

11. The method of claim 1 further comprising:

in the event that said first and second mathematical objects have the same type, merging said first mathematical object into said second mathematical object; and

deleting said first mathematical object.

13. The method of claim 9, further comprising:

detecting selection of a table object;

attaching a control panel to said table object, said control panel providing a user interface for adjusting data in said table object.

14. The method of claim 9, wherein said first mathematical object is a user-selected mathematical object.

15. The method of claim 14, further comprising:

showing a link handle on said graphical user interface at the proximity of said first mathematical object;

detecting dragging on said link handle by a pointer;

creating a visual indication, said visual indication originating from said link handle and extending along said pointer;

detecting the dropping operation by said pointer; and

identifying said second mathematical object as the mathematical object that said dropping operation is performed thereon.

16. The method of claim 9, wherein identifying said first mathematical object comprises:

detecting a drawing by a pointer starting on a mathematical object; and

identifying said mathematical object as said first mathematical object.

17. The method of claim 9, wherein identifying said second mathematical object comprises:

detecting a drawing by a pointer ending on a mathematical object; and

identifying said mathematical object as said second mathematical object.

12. A method for relating a first mathematical object and a second mathematical object in a computing apparatus having a graphical user interface, said method comprising:

receiving instructions via the graphical user interface to relate the first mathematical object to the second mathematical object;

merging said first mathematical object into said second mathematical object;

deleting said first mathematical object.

18. A method for creating a second mathematical object from a first mathematical object in a computing apparatus having a graphical user interface, said method comprising:

identifying a first mathematical object;

creating a second mathematical object using data of said first mathematical object;

linking said first mathematical object to said second mathematical object; and

creating a visual link between said first mathematical object and said second mathematical object.

19. A method for relating at least two mathematical objects in a computing apparatus having a graphical user interface, said method comprising:
