TI-84 Plus CE Wish List and YouTube Shorts

TI-84 Plus CE Wish List and YouTube Shorts



TI-84 Plus CE Wish List



Disclaimer:  I do not work for Texas Instruments nor do I know when (or if) TI is working on and publishing operating version 5.9, 6.0, etc.  This is my opinion only (the opinion of a math and calculator enthusiast).


This focuses on the United States version of the TI-84 Plus CE series.


I would like to see the following in the next update:


1.  Simplification of radicals and square roots.*   Currently the series only has decimal approximations.


Examples:

√440 returns  2 * √110

√75 + √125 returns 5 √5 + 5 √3


2.  Mathematical operations returning exact results in terms of π.*  Like #1, the series only has decimal approximations.


Examples:

In radians mode,  cos^-1 (1/2) returns π/3

2 π - 3/8 * π  returns 13/8 * π


3.  Base mode and conversions.  With the exception of the classic TI-85 and TI-86, the TI-80s do not have a base mode nor base conversions.  I would like to see that added, make room under the test menu.    


4.  More colors than 15 please.   Maybe an RGB (red-green-blue) function in the TI-BASIC programming language?  


With Gratitude to TI.

* FYI:  #1 and #2 are available on the TI-83 CE Premium from France.  



YouTube Shorts



From time to time, I will post YouTube short videos (60 seconds or less) to my YouTube channel (which has been a long time starving for content):

My channel covers primarily math and calculators.
