The contacts might be bad or battery too low. If you have a reset button on it try pressing it.

How do i get my alpha key work


The TI-84 is a bit of a pain this way. You need to access the logBASE function either through the catalog or the MATH menu. You can't spell the function name as with some other calculators.

Press MATH, scroll down to the logBASE entry, then press ENTER. This will put "logBASE(" into the entry line. You can then enter the arguments and press ENTER to calculate the result. For example, to calculate the log base 2 of 8, press MATH, down-arrow a number of times to logBASE, press ENTER 8 , 2 ENTER. This should give you 3.

Key working alpha


The alpha key activates the alphabet keyboard and a few extra symbols. To access the MATH menu and the ToFrac command, press the key below the ALPHA key. The key is marked with MATH.
On the TI84PLUS with the newer operating systems (version2.5x), the APLHA key opens up a few functionalities. That is not available on the TI 83Plus.

Where is the math button on the casio fx-9750G11


It is a calculator and prqactically every button is a MATH button. It depends on what MATH you intend to do. Put the calculator in Run/Mat screen then press the OPTN key. You will see several tabs. Press the function key under a TAB and explore what is offered. Go through all the keys (F6 also) and see what the new tabs do.
In general it is most helpful to read the manual that shipped with the calculator.

How do you enter fractions into the ti-84 plus?


It depends on the version of the Operating system.
This works for Older and newer OS
Enter numerator, press the [division key], enter the denominator, press the [MATH] key and select [1:ToFrac] [ENTER]

With the newer OS versions 2.53 MP and following you can manipulate fraction more easily. If your calculator MODE is set to MathPrint, you can use the [Alpha][Function keys] to access some functionalities

This gives you access to the Tabs shown in the following screen capture.
k24674_120.jpg
Press 1:n/d for improper fractions or 2:Un/d for mixed numbers.
Press [ALPHA][Y=/F1] to activate the FRAC menu. You get a template for a stacked fraction, where you enter the numerator and denominator at their right places. Note that fractions are always reduced to their simplest forms.

There's no DMS button and I need to convert minutes and seconds to degrees. How do I do this?


Press the MATH key to bring up the Math menu. Select "Real" and then "HMS->". This function takes an angle in DDD.MMSS format and converts to decimal degrees. The "->HMS" function goes the other way.
