A calculator is a hand-held inexpensive electronic device used to perform the operations of arithmetic. The simplest calculators can only do addition, subtraction, multiplication, and division, while scientific calculators can handle exponential operations, and trigonometric and logarithmic functions.
Press second (2ND) and then memory (MEM, above +). Then select the seventh option, Reset.... In order to delete everything, use the arrow keys to select ALL on the top and then press enter to select All Memory....
Once a program has been deleted on a TI-84, it is no longer in the calculator's memory. You would have to get the program from where you got it, or, if you programmed it, remake the program.
Press the "Y=" button and there are spaces to graph up to ten  equations. For example, y1 = 2x and y2 = 3x + 5. If a line is not  showing up, make sure the equals sign for that equation is  highlighted. (Select the equals sign by moving the arrow keys and  then press Enter.)
All you have to do is multiply 0.25 by whatever the number is.

There are online graphing calculators. However, as of writing, there is no emulated TI83 that runs within your browser. On the other hand, if you have a Ti83, it is possible to copy its ROM to run an emulated TI83 on your desktop via one of many emulators.
Every mobile phone is different.

A graphing calculator (also graphics / graphic calculator) typically refers to a class of handheld scientific calculators that are capable of plottinggraphs, solving simultaneous equations, and performing numerous other tasks with variables.
Example: Turnaround Time: P1 : 24, P2 : 27, P3 : 30 - Average TT: (24 + 27 + 30)/3 = 27
To graph it: Click "Y=" (top left of calculator)go to the top left of the screen and click "x="type in "8" and hit graphHope it helps :)

The TI-83 does not have the cot button, however, if you type 1/tan( then this will work the same as the cot since cot=1/tan. The other way to do this is to type (cos(x))/(sin(x)) where x is the angle you're looking for. This works because cot=cos/sin
