Top 20 Texas Instruments TI-84 Plus Calculator - Page 9 Questions & Answers

See Laurent series of this function:z^(3)exp^((1/z-1))=z^(3)+z^(2)(1-z)+(z(1-z)^(2))/2!+1-(1-z)^(3)/3!+...You can see it has an essential singularity at the origin

Press MODE then select the number of places on the second line.

To obtain non integer results into a fraction form you must insert at the end of the command line the key sequence [MATH][1:>Frac][ENTER].The calculator cannot give you results expressed as radicals; at least not natively. You will have to look for a program that does that. Search the education.ti.com or the ticalc.org sites for such program.

Use the ^ key just above the divide key. For example, to raise 2 to the 3rd power, press 2 ^ 3 ENTER and see 8.

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

Use the (-) key just to right of the decimal point key.

Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

Is it somehow preventing you from graphing, or are you simply not getting the graph you expect?Most likely you have the angular mode set wrong. You probably want it set to radians. Press MODE, move to the third line, highlight RADIAN, press ENTER, then 2ND [QUIT].If it's not the angular mode, please reply to this post and give an example or two.

Press 2 ^ 1 0 ENTER and see 1024

The third-party programs do not usually run on the native OS. You meed another shell program which when installed allows the execution of 3rd-party programs.

Press [2nd] ZOOM, scroll down, and select AxesOn.

If you're in the MATHPRINT mode, press2ND [COS^-1] ( 8 - 3 2ND [sqrt] 2 1 right-arrow ) / 2 5 ENTERIf you're in the CLASSIC mode, press2ND [COS^-1] ( 8 - 3 2ND [sqrt] 2 1 ) ) / 2 5 ENTERIn either case you should get an answer of about 103.

Memory is insufficient to perform the instruction or function. You must delete items from memory before executing the instruction or function. Recursive problems return this error; for example, graphing the equation Y1=Y1. Branching out of an If/Then, For(, While, or Repeat loop with a Goto also can return this error because the End statement that terminates the loop is never reached.

Replace the batteries

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible. Does it?

Enter the base as the second argument, following a comma. For your example, enter it as logBASE(X,2) .

The key allows you to enter different variables, X for function graphs, T for parametric graphs, Theta for polar graphs and n fro sequence graphs.

3x-7y=2 is an equation of a line. That line doesn't go through the point (6, -7) though. Are you looking for the equation of a line through the point parallel to the first line? Perpendicular?

Transferring data and programs to the calculator requires a lot of energy that almost dead batteries cannot provide. Change batteries and try the transfer again using TI Connect. To transfer from a similar calculator the receiving one must be in RCV (receive mode).
