Code:
Note : D is digits of precision
How would I do the same thing with sequential functions or y-vars of any type (on the Ti-83+)?
like...the u, v , and w things.
EDIT :
With some help with people in SAX, I got this code :
Code:
However, I get garbage output.
for A=1 : B=2 : C=-3 : D=0 :
I get : x={7,-9},
When I should get : x={1,-3}
