To find the inverse cosine (arccos) on a TI-84 calculator, press the "2nd" button, then the "COS" button, which is located above the "COS" key on the calculator. This will bring up the arccos function. Enter the value for which you want to find the inverse cosine and then press "ENTER" to get the result. The answer will be displayed in radians by default; you can change the mode to degrees if needed.

Where is arcosine on a TI-84 calculator?
It is labeled as "cos-1" on the calculator. But arcosine and inverse cosine are just two names for the same thing.
How do you find inverse cosine on a TI-84?
I don't know this model, but most calculators have one or more special function keys, which may be labelled Shift, Function, Inv, etc.; you have to press this key before you press the cosine key. This is correct, you have to press the "2ND" button (top left) and then "COS". You will notice that "COS-1" is written above the "COS" button- this is the function you want.
Where is the inverse function on the TI-84 Plus?
On the TI-84 Plus calculator, to find the inverse function, you can use the "Y=" editor to define your function. Once you've entered your function, press the "2nd" key followed by the "Y=" key to access the "Vars" menu, then select "Y-VARS" and choose "Function." You can find the inverse function by using the "x" variable or applying the "1/x" functionality, depending on the context. For direct inverse calculations, you can also use the "Calc" feature to evaluate the inverse at specific points.
How do you find the inverse log using a TI 84 plus?
The 2nd function of the log button is the inverse log. Press 2nd log, which displays 10^( on the screen. Put a number after the opening parenthesis.
Is there any games for the TI Nspire?
You can play Ti-84 games with the 84 keypad but I have yet to find games for the n-Spire CAS. So just download TI-84 games and use the 84 keypad.
How do you find sec on TI-83 Plus?
There isn't a sec key on the TI-83 Plus. Secant is 1/cosine, which is what is used to find secant on a TI-83 Plus. For example, to find the secant of 4, enter 1/sec(4).
Is the Texas Instruments TI 84 Plus Graphics Calculator good enough for any college math course?
The TI-84 Plus Graphing Calculator could easily carry a student from the high school algebra to any upper level college math course such as trigonometry or even certain sciences such as physics. It has the sine, cosine, and tangent buttons to help a student find the information and with its speed 2.5x that of the TI 83, it can get to the solution even faster.
What is the TI - 84?
The TI-84 is a graphing calculater. It is mostly just an update to the TI-83 calculater.
How do you solve matrix on ti-84?
To solve a matrix on a TI-84 calculator, first, enter the matrix by pressing the MATRIX button, then select EDIT to define your matrix dimensions and input the values. After entering the matrix, exit the edit mode, then access the MATRIX menu again to select your matrix for operations like finding the inverse, determinant, or performing row operations. For example, to find the inverse, select the matrix, then press x^-1 and hit ENTER. The calculator will display the result.
