If you were skimming through the website, you probably found some funny codes (like oY= or --8) and you can't figure out their meaning!! Well, here are your answers! Since some of the symbols on the TI calculator can't be reproduced on Geocities, here is some close looking symbols used to distinguish them.
On the | Y= | button
|\Y1 = 1 / (1--X)|
|^ See this slash? Well, if you go on top of it and hit enter, you can get many different graphing modes.
Here they are, represented in order of appearence:
\ Y1 = connected
:\ Y1 = bold line
>\ Y1 = greater than values
<\ Y1 = less than values
-o Y1 = lined ball-end
o Y1 = not lined ball-end
...\ Y1 = dotted
|Distinguishing the difference between a minus (subtraction) sign and a negative sign:
In Geocities language, negative signs and minus signs can get confusing. Here is a simple way to distinguish one from another:
-- Minus Sign (Bigger in length on the calculator. Located above the +sign)
- Negative Sign (Smaller in length on the calculator. Located to the left of the | ENTER | button
Depending on what MODE you are on (Func, Par, Pol, or Seq), the calculator diplays different variables.
Funct = X
Par = T
Pol = Q (Theta)
Seq = n
# = Square Root
