To convert a decimal to a fraction on the TI-84 Plus, enter the decimal number and then press the MATH button. From the menu, select the "Frac" option (usually option 1) and press ENTER. The calculator will display the decimal as a fraction in its simplest form. If needed, you can also use the "→Frac" command after entering the decimal.
To convert degrees and minutes to decimal degrees on a TI-84 calculator, first enter the degrees as a whole number. Then, add the minutes divided by 60. For example, for 30 degrees and 15 minutes, enter 30 + (15 / 60) and press ENTER. The result will display the decimal degrees, which in this case would be 30.25 degrees.
Yes, you can convert decimals to radicals on a TI-84 Plus calculator using the "MATH" menu. Select the "NUM" option and then choose "√" for square roots or "nCr" for other roots, depending on your needs. Input the decimal value, and the calculator will provide the radical form if it can be expressed as such. However, not all decimal values will have a neat radical equivalent.
This is from a TI-84: Once you have the decimal on your screen, click MATH (on the left side of calculator). Then click 1-FRAC and hit enter one more time. That will give you the fraction.
Convert the fraction into a decimal. Multiply the decimal by 100.
The TI-84 is a graphing calculater. It is mostly just an update to the TI-83 calculater.
Yes, the TI-84 is allowed during the ACT.
Unfourtunately, it is not possible to expand with the TI-84. Only the TI-89 can expand polynomials.
Sorry, but no, to my knowledge there are no shells for the TI-84=CSE, and there probably will never be, the last descusions about being in 2006, and the TI-84+CSE is not compatible with the old TI-84 or even TI-84+SE programs. I am sorry to say but you will never have complicated games for this edition of the TI calculators but there are some simple games that don't need shells, such as tetris, worms etc:
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.
