This is mainly an experiment in user input processing on the TI-84+ CE, but it may turn into a larger project if you want it to!
It is based (sorta) off of Terminal on my Mac, and has a very similar style of commands. Full command list/documentation will be posted ASAP.
Short-Term Project Goals:
1) full command documentation
2) more commands
Long-Term Goals:
1) More commands
2) Optimization/neatness
3) User Friendlyness
I know this could be optimized/made neater, and it is very small, but keep in mind I haven't had much time lately.
Code:
Here's a small GIF I made (My friend wanted it to be a SIRI-like program
)
If you have a suggestion, PM me or post a comment in the thread!
Documentation:
grph:
..Parameters:
....Slot (1-3), then Expression
......Ex:
grph -1 sin(X)
a’, then equality/inequality
Ex:
grph -a sin(X)<cos(X+Z)
Use “Z” instead of Y.
disp:
Parameters:
‘c’, then constant name.
Constant list:
e (Euler’s Number)
Pi
More coming Soon
Example:
disp -c pi
say:
Parameters:
Whatever you want the program to spit back out at you.
list:
Parameters:
list num (1-3), then what you want in your list
Example:
list -1 {1,2,3,4,5,6,7,8,9,10,11
‘r’ , calculates linear regression
