RE: New Blog Entry: Fun with the HP 12C
Combining both of Valentin's ideas we can define the Taylor series of sin:

0 CF0
1 CFj
x<>y CFj x<>y
2 CHS ÷ 3 ÷ CFj
x<>y CFj x<>y
4 CHS ÷ 5 ÷ CFj
x<>y CFj x<>y
6 CHS ÷ 7 ÷ CFj
(...)
x<>y CFj x<>y
12 CHS ÷ 13 ÷ CFj

Then we can use this short program to calculate sin(x):
Code:
1/x
1
x<>y
Δ%
STO i
NPV

Cheers
Thomas
