About the Sequence aplet
The Sequence aplet allows you to explore sequences.
You can define a sequence named, for example, U1:
•
in terms of
n
•
in terms of U1
( n –1)
• i
n terms of U1
( n –2)
•
in terms of another sequence, for example, U2
( n )
•
in any combination of the above.
The Sequence aplet allows you to create two types of
graphs:
–
A Stairsteps graph plots n on the horizontal
axis and
U
n
on the vertical axis.
–
A Cobweb graph plots
U
n– 1
on the horizontal
axis and
U
n
on the vertical axis.
