Thread: Anyone around here fluent in ti83?

I was just wondering. I tend to do most of my programming on it since it happens to be on me at all times and is thus more convenient than c++. I'm currently trying to make a program to handle the "ambiguous case of the law of sines" that I'm having difficulty with. Here's the code.

Code:

:Lbl {theta}
:0->A:0->B:0->C:0->E:0->F:0->G:0->H:0->{theta}
: Disp "SIDE?"
:Input A
: Disp "SIDE?"
:Input B
: Disp "ANGLE OPPOSITE SECOND SIDE?"
:Input {theta}
:A(sin({theta})->H
:If B<H
:Then
: Disp "NO SOLUTION"
:If B>H and  A>B
:Then
:Goto A
:If B>H and A<B
:Then
:Goto B
:Lbl B
:asin((Asin(B))/B)->C
:180-({theta}+C)->D
: (Bsin(D))/sin({theta})->E
:ClrHome
: Disp "SOLUTIONS:"
: Disp "SIDE 1: "B
: Disp "ANGLE 1: "{theta}
: Disp "SIDE 2: "A
: Disp "ANGLE 2: "C
: Disp "SIDE 3: "E
: Disp "ANGLE 3: "D
:Pause
:ClrHome
:Goto {theta}

The spaces before some of the commands are because the board thought that they were smileys. {theta} means greek letter theta.

The code is for the ti83 plus silver edition in case it makes a difference.

Where exactly do you enter codes for ti83? Is it relatively easy to learn?

>> Where exactly do you enter codes for ti83?
there is a little text screen that pops up in the calculator

i was gonna learn how to preogram t6he graphing calculator too, but typing with the numpad and looking in that small screen ........ed me off(and most of my progs weren't working eirther) so i quit.

The Ti83 (without plus) sucks.

Do you ask why? Try this:

Plot the graph y = 1/x
Press "calc"
Calculate the derivative for x=0

Poof!!

The screen goes blank and the memory with all data and saved programs is cleared.
To make the calculator work again, press reset, insert the batteries backwards, press the on button, insert the batteries correctly and start the calculator.

At my school, almost every student used the Ti83. I was using Casio and made a lot of fun of that bug.

Texas Instruments is what ti stands for right? and 83? as for that number, ill hafta see what my schoiols calculator is.

Just hit the program key "PRGM" then go to "NEW" then "CREATE NEW". Now just name the program and write the code.

Its not hard to learn, if you have the book that came with the calculator it can teach you the basics.

Personally I think its a pain to write programs on the calculator. Mainly because of the key setup.

i find it hard to find any keys on the new TI stuff. i actually had a tough time finding the equals sign. problem was, on this one, i needed to press shift (or 2nd functions for the rest of you)

I have a Ti89... Is it true that some calculators aren't allowed on
ACT/SAT type tests (College Placement Tests... ya know..) If so,
is the Ti89 one of them?

No, Ti 89 calculators are not allowed on the ACT niether are Ti 92s. Any calculator with a QWERTY key format or wireless communication device, as well as, calculators with built-in computer algebra systems are prohibited.

If you completely cover the infrared port on wireless communication devices they are allowed.
