GUEST... thank you very much.. works fine with my voyage ;)

Your right you should be in degree mode. However, my guess is you are somehow entering in cot wrong in your calc. Recall cot = 1/tan! In your graphing calculator enter: 35(1/tan(61) = 19.4. Hope this helped!

For curly braces {} use 2ND ( and 2ND ). For square brackets [] use 2ND multiply and 2ND plus.

Hi
The TI82 is a bit old Technology and if you did not use for a few years the screen is dead its a common problem with this model and the TI83
sorry for not been a big help

DOMAIN ERROR: - You specified an argument to a function or instruction outside the valid range. This error is not returned during graphing. The TI-84 Plus allows for undefined values on a graph. - You attempted a logarithmic or power regression with a LX or an exponential or power regression with a LY. - You attempted to compute GPrn( or GInt( with pmt2 < pmt1.

Use the division key.

The simplest way would be to create a table where each x-value has a y-value that is the residual at the corresponding x. With a 2-list data set you can plot you residual plot.

Question edited for full 'MAKER, model (what it is)'. Question moved from MISC to correct category. Here on the maker website https://education.ti.com/en/products/calculators/graphing-calculators/ti-84-plus-ce-python/applications https://www.google.com/search?q=TI-84+Plus+CE+Apps ..

Let's see, 10% interest per year on $100 for one month. That's 10/12 of a percent interest on $100 is $0.83, added to $100 is $100.83 (with a bunch more 3s at the end). Clearly this is the correct answer. What answer are you expecting? The future value at the end of one year instead of one month?

that is not so: when you press the square root key, the calculator automatically inserts the opening parenthesis (the left one). It does so for all the built-in functions. With MathPrint parentheses are not necessary because of the open boxes.the content of the box is implicitly enclosed in parentheses.

4 MATH 5 5 7 ENTER

will calculate the fourth root of 57.

Use the xth-root function to compute any root. It's the fifth entry on the MATH menu, which you can get by pressing the MATH key. The fourth entry on the same menu gives you the third root without needing the 3 to be specified.

For example, to compute the 5th root of 32, press 5 MATH 5 3 2 ENTER.

Hello, If by reset you mean revert to the default settings, press [Zoom][6:ZStandard] If on the other hand, you want to play with the window dimensions press [WINDOW] and change the values of Xmin, Xmax,Ymin,Ymax. Make sure that Xmin Less than Xmax, Ymin less than Ymax. If domain is positive set Xmin=0., If range is positive set Ymin =0. Hope it helps.

type 15 then click a button that looks like this^. then 365. Then hit enter. it is like a normal clcutor except with more function. Sometimes you need to use the 2nd and the alpha button to do some functions.

The most likely thing that happened was it fell, or you burned out the motherboard.

97.75

I encountered this same problem with the TI-84. Turns out you have to put your P (Percentage) as out of one hundred. For example. With my problem I had; Trails: 13 P: 53/100 X Value: L1 (List 1) And then it posted my probabilities to the L2 list. For some reason if you just put 53, or whatever your percentage of success in, it won't calculate.

There is no percent function. To enter 20, simply press "." then "2".
