Question about Texas Instruments TI-89 Calculator

Error message i have a TI-89 titanium. I'm trying to do my calculus homework and when i have my calculator on function, radian, exact, all that .. and when i go to graph (x)/((x^2-4)^(1/2)) .. in words that means "X divided by the square root of X to the second power minus 4 .. and every time i press the graph button and error message appears and tells me "dimension" .. what does that mean .. please help me out .. thank you, friendly011511

Dimension error meaning that a list or matrix index is not valid. For example, if the list {1,2,3,4} is stored in L1 then L1[5] is a dimension error because L1 only contains four elements. Finally, it is easy to solving your problem. See captured images

Calculus cos^-1 Domain Error


If you're in the MATHPRINT mode, press
2ND [COS^-1] ( 8 - 3 2ND [sqrt] 2 1 right-arrow ) / 2 5 ENTER

If you're in the CLASSIC mode, press
2ND [COS^-1] ( 8 - 3 2ND [sqrt] 2 1 ) ) / 2 5 ENTER

In either case you should get an answer of about 103.

Error memory when loading calculus made easy on ti-89 titanium


You may get Memory Error when you try to access an archived variables. From the other hand Memory Error message is displayed if there is not enough free RAM to access the archived variables. For correcting Memory Error message use the 2ND then MEM to check RAM free size and 2ND then VAR-LINK to determine the size of the archived variables that you want to access. As the third step for correcting this problem deleting unnecessary variable from RAM and archiving large variables or programs. By the definition, the RAM free size must be larger than the archived variables

I try to install software on a ti-89 and the dimension error when I open the program. Faso also commonly when derived from sin (x) the result is not cos (x) more so, 0.017 cos (x)


I do not know the program you installed, so I will skip the part.
As to the derivative of the sine function, your result is correct if the angle unit is degree.
d(sin(x))/dx = cos(x) is true only if the angle unit is the radian. In degrees, you would have a factor Pi/180 which is 0.174532925. I suggest you consult a calculus book to understand where that factor comes from.

Some of my class set of Ti - 84 silver aren't computing sine and cosine correctly. I've tried clearing RAM and looked at settings. Please help!


I have answered many questions asked by teachers and professors, and very few, if any, deigned to rate the posts. Why do I set myself up for yet another disappointment: I just like to help.

Anyway, the most common source of errors with computation of trigonometric functions is the angle unit. On Ti 83/84Plus (SE) calculators there are two angle units: the degree and the radian.

To verify which angle unit is set as default on a calculator, press MODE. You will see the following screen. The relevant line is the 3rd. On the screen RADIAN is highlighted, meaning that all angle values you feed to trigonometric functions are interpreted as radian measures.
Similarly, all values returned by inverse trigonometric functions are in radians.

I do not know what grades you teach, but if you are doing any differential calculus, the only appropriate unit is the radian. Only for the radian unit is the derivative of sin(x) equal to -cos(x). For the degree, you must introduce a factor to adjust (as a change of variable).

Set all your calculators to use the angle unit you are using in your teaching, and there will be no unexpected results.

Dec to hex conversion


Not sure if TI-89 mode keys are the same, but here's the solution for that calculator:
1. Hit the mode key
2. Hit F3 to get tot Exact/Approx (might be different for 89T).
3. Set it to Exact.
4. Take a look at T-89 manual pages 327, 328, 329.
Nice of TI to NOT include that in the manual, huh?
