Inputting Ans Memory Contents into an Expression
Example: T
o perform the calculations shown below:
123 456 579
(Continuing) 789
Using PreAns Memory
Example: For T
k+2
= T
k+1
+ T
k
(Fibonacci sequence), determine the
sequence from T
1
to T
5
. Note however, that T
1
= 1 and T
2
= 1.
T
1
= 1

(Ans = T
1
= 1)
T
2
= 1

(Ans = T
2
= 1, PreAns = T
1
= 1)
T
3
= T
2
+ T
1
= 1 + 1
(PreAns)
(Ans = T
3
= 2, PreAns = T
2
= 1)
T
4
= T
3
+ T
2
= 2 + 1
(Ans = T
4
= 3, PreAns = T
3
= 2)
T
5
= T
4
+ T
3
= 3 + 2
Result:
The sequence is {1, 1, 2, 3, 5}.
