These circles were created as individual parts of sequences. The Sequence[...] command does not only allow you to create sequences of numbers, but of any objects. Also, multiple objects can be created by using the spreadsheet. [br][br](This side originally created by [url=https://www.geogebra.org/themadmathematician]Jonas Hall[/url])

Creating multiple objects with partly the same characteristics can be useful for: [br][br][list][*]Creating many random objects for Monte Carlo Simulations (Use a random element in the command). [/*][*]Creating custom labels, custom grid marks, custom grids etc [/*][*]Exploring many objects at once[/*][*]Any situation which would normally require a FOR loop. [/*][/list]

The construction above uses the following KEY ELEMENTS: [br][br][list][*][b]The command that creates the circle[/b]: In this case it is the command Circle[(p, 0), p] for some values of p.[br][br][/*][*][b]The Sequence Command[/b]: In this case we let p run from 1 to 3 in steps of 0.2 so the command is Sequence[XXX, p, 0, 3, 0.2] where the XXX is the stuff you want to repeat. [br][br][/*][*][b]The complete command is[/b]: Sequence[Circle[(p, 0), p], p, 0, 3, 0.2]. Please note that p is not a local variable and should be one you haven't used before or you'll get unexpected results. The result is a list of your objects and can only be manipulated as a list e.g. with regards to color etc. [br][/*][/list]
