GeoGebra笔记10 :Sequence序列

Sequence(表达式,变量,初值，终值,增量)
Sequence(n^2,n,1.10,0.2)

stroke1用笔划线
Sequence(Rotate(stroke1,(n 30)“alt+O”),n,1,12)
Sequence(Rotate((stroke1,(n 30°)),n,1,12,1))
二维序列：
Sequence( Sequence(Vector((i,j)), i,-5,5),j,-5,5)

列表的运算：

{}*5
{}+{}
sunm({})
Length(List)
Element(List,1)
First(List,3)
Last(List,3)
Take(List,3,10)
Append
Insert
Remove
