Hi,I am using my ti-84 plus and ti-84 plus ce-t but yet is still can't find this symbol: ℕ
It is also used like this: ℕ1 or ℕa letter or another number would go here
Pls help.thanx a lot!
That is indeed a finance variable. You can find it by pressing [APPS][ENTER][RIGHT][ENTER].
Hello, I am using the TI-84 Plus CE. I wanted to know if there was a way for the inverse trigonometric functions to return both angle possibilities.
For instance, typing (in degrees mode):
sinֿ¹(√(2)/2) returns 45, which is a possible angle. However, 135 is also a possible angle. I was wondering if there was a way for me to make the calculator give back both possible angles.
Thank You so much!
Try this:
Prompt A
sinֿ¹(A→A
Disp A,A+90(A>0)-90(A<0Does anyone have a font file for the TI-83+ font? I've looked everywhere and am unable to find it. Thank you!
does anyone that happens to know a way to program triangulation on a ti 83 plus. Ive been looking on google to no help. If anyone knows a way it can be a big help.
2nd->stat->right arrow->up arrow->enter
or
2nd->0 button (catalog)-> Alpha-> ) button (L)-> enter
You now have the list symbol.
Just as an added note: You do not need to include the "∟ " unless you are recalling from a list. Storing to a list it is not needed. See the Optimization section on this page.
Also the hang man game doesn't work it just shows a Domain or Undefined error. The Snake game doesn't work since it just shows up and disappears
According to this wiki, the Try command is on all the calculators, but I can't find it - even in the catalog. Does this command not exist anymore or what? If so, what can I do to simulate the try command (i.e., try a command and see if and error was given without stopping the program)?
The Try command is only available for TI-89 series or above calculators, which use 68k BASIC instead of regular BASIC for their programming language. Unfortunately, you cannot download the Try command for the 83 series.
The solution to a complex problem is often a simple answer.
As kg583 said, it is only for the 68k BASIC. This can be seen in the fact that Try is in the 68k Command Index but not in the Command Index. So when you say that the site says it's available for all calculators, that is not what it says. It says it is available for all calculators running 68k BASIC.
Is there such a code in TI-Basic that can make a program to solve for x or whatever variable without automatically assuming it has a value? Is it possible? (You know if you try to input an equation with a variable, instead of solving for the variable it gives you an actual answer, assuming the variable equals 0 unless a value is stored in that variable previously by a program or manually. I was hoping to see if such a program can be created as to input an equation that can solve for a certain variable, not just assuming it’s value based on previously stored values.).
U know like 2x=4 after solving x=2.. that’s what I mean that u input 2x=4 and the calculator tells u x=2, but I was wondering if such a program can exist as to input more complicated equations?
What you're looking for is a CAS, or Computer Algebra System, which does not exist on the TI-83+ series. Certain Nspire models do have a CAS, but I don't know of any CAS's made in TI-Basic or otherwise for use on a regular TI-83.
The solution to a complex problem is often a simple answer.
Yeah, solve( can sometimes do that. The capabilities are limited though as you need to know some interval where the solution exists, and the equation needs to be put into f(x) = 0 form.
Thanks I’ll look into it, I’m going to experiment with some programming to see if it’s possible to solve for a variable that remains that way.
I am actually working on a pretty fast BASIC CAS currently, and I would really appreciate any results you may find from said research, provided you are comfortable with sharing them.
I can't seem to find a way to determine if a number is rational or not in TI-Basic. I know that ►Frac converts a rational number to a mixed number and converts an irrational number to a decimal. Is there a way to know if a number is rational or not in TI-Basic? Will I have to use Decimal to Fraction?
Okay, thanks!
I need a way to round the simple way (Im a newbie so i might be asking dumb questions) so that for example:
if i round 82 by 10 i will get 80 or if i round 34 by 10 i will get 30 another example:
(If there was a command to do this) round(98,10)=100
(A real quick answer would be awesome!)
Type this command if you are rounding X to the nearest N place value:
Nround(X/N,0
For example, to round 82 to the nearest 10, type this:
10round(82/10,0
The answer should be 80. Hope this helps. Also, you can find the round( command by pressing [MATH][right arrow key][2].
Thx it helped!!!
oh and if i answered late its cuz i went to sleep after i asked :)

Do you know how wide the voyager 200 screen is? (In pixels)
240x128 pixels , according to the ticalc website. Hope this helps.
