General Calculator Help / TI-nSpire CX CAS , noob user questions + rants
« on: February 09, 2014, 10:06:16 pm »
So I got the CX CAS recently, and I've been using it a bit.

Questions:
* Handheld Setup->Font Size : It doesn't seem to change the font size of the "stack"? What does it change? And did it change the "stack" font size before I upgraded the firmware to the latest?

* Can I "wash away" math print and get an expression in full "programming style" syntax?

* Marking / selecting text. MAN, how did they ever choose such a stupid colour for showing selected text? It's practically invisible against the white background! It is clearly visible if I rotate my CX 180 degrees (yaw), or roll it a bit...  I went as far as thinking that my display was mounted wrong. Is there a way to change this selected text colour?


Rants (please feel free to comment)
* WHY have they made the access and viewing of variables and functions (when you plot) so hard? What's wrong with a list on which you can select, delete and preview variables and functions? This is SO stupid! It took me long to figure out how to delete a function!

* I found myself feeling "strained" using the CX CAS. At first I thought it was the CX CAS that was "stupid", but probably it is my brain that is slow to learn. I finally did a timed trial entering a long math expresion. The CX CAS was quicker than the rest! (330, 48GX, 89)

Other Calculators / What calculator will let me do multi (word wrap) line math expression editing?

HI!

Background:
Ever since I went from the HP 48GX to the TI-89 I was really disturbed by the TI-89:s inability to let me edit a really long calculation (34+53-343/34...) on multiple lines (word wrapping)!

The HP 48GX lets you full screen multi line edit a '3242+34324+324+23+4...' object with leftshift->edit.

So on my (then) new TI-89 I had that big screen, but the calculator only let me edit the expression on one row. This I find is a really BIG mistake on the TI-89:s user interface.

Well, as time passed on I learned to use Apps->Text Editor instead. Just make a quick Copy and then 2ND |<-|->| to move between Home and Text Editor, using Copy and Paste. Not ideal, but it works.

I also own a Casio ClassPad 330. I don't know this calculator as good as the TI-89; I mainly bought it because it can do fourier and laplace transformations. But, it seems to have the same problem as the TI-89. With the 330's even bigger screen, I still can't make multi line editing. Yes, as with the TI-89 I can copy the expression to the Program Edit. But since "app switching" isn't as easy and quick as with the TI-89, this is really tiresome.

So fast forward to January 2014. I'm looking to buy a new calculator. Main contenders are the HP Prime and TI-Nspire CX CAS.

I've tried out both calculators emulators on my PC. But again, I can't seem to find ANY way or editor on those that let me do multi line editing?

Every editor or "viewing mode" I try out does NOT wrap the lines. Not even in programming editor, notes, etc... Just that freaking one line and scroll arrows!!!

For me, as a student using the calculator mainly for "calculating", preparing and doing exams, this is totally disturbing! How can the calculator makers miss such a obvious thing that is at the core of what a calculator is intended to be used for?

****Since my calculator has to be "clean and cleared" for exams, I can't use any extra software on the calculator, such as an extra editor etc.****

Am I wrong? Am I missing something on any of the calculators?

What do you think?

Since I own the original TI-89 I'm thinking of buying a TI-89 Titanium, is this my only option?
