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)
•in 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.
