WHAT IS USED FOR THE EQUAL TIME


The calculator is doing exactly what you tell it to,

You first input 1.06. Then you press the y*x key, which tells the calculator to raise the previous number on the stack to the 1.06 power. Then you input 10. The result of all this is 10, as your calculator shows.

If you want to raise 1.06 to the tenth power, press 1 . 0 6 ENTER 10 y^x.

My 12c shows 1.7908 for the above.

How to find pH


Do you have the concentration? if YES, you CALCULATE the pH with the relation
pH=-log(c) where c is the value of concentration in mol/L.
ex: c= 3.57x10^(-6)
pH: (-) [LOG] 3.57 [2nd][EE] [(-)] 6 [ ) ]
Here you have 2 change sign key press [(-)]

If you have the pH, and want to calculate the concentration that yields that value of the pH you proceed as follows
c= 10^(-pH)
Ex pH=8.23
c: [2nd][LOG] [(-) 8.23 [)]

Here is a screen capture to show you both calculations

What function should it be on to get a whole number answer for division problems EX: 15 divided by 2


15 divided by 2 isn't a whole number.

If the calculator is showing a fraction and you want to see it as a number, press the S--D key to switch between symbolic and decimal values. To have all results appear in numeric form, press SHIFT MODE 2 to select the LineIO mode.

If you want to set the calculator to show only whole number, press SHIFT MODE 6 0 to select FIX 0 display mode.

No reset needed. To specify the number of digits after the decimal point, press SHIFT MODE 6 and then the desired number. Alternatively, press SHIFT MODE 8 and then 1 or 2 to select "Normal" mode.

I assume you know how to define your matrix, but I will repeat it here for others who might not know. You can skip to Calculation
1.Turn Calculator ON. If there are no icons, press [MENU].

Data Entry

2.Use arrows to highlight [MAT] icon. Press [ENTER]
3.Highlight the first line where it says Mat A. Use the right arrow to enter the dimensions of Matrix A. Enter 3 and press [EXE]. The cursor moves to the second dimension. Press 3 and press [ENTER].
4. The matrix entry screen appears.
5. Enter first matrix coefficient a_11 and press [ENTER]
6. Enter a_12 and [ENTER]
.....
Key in last coefficient a_33 and press [ENTER]

Calculation
Press [MENU] and [RUN]
Press [OPTN][F2:MAT][F3:Det] Command echoes on screen as det
Press [F1:Mat] echoes on screen as Mat; screen shows det Mat

Solve Permutation and Combination


Turn calculator ON
If you do not see icons, press MENU key.
Use arrows to move focus on the RUN application and press EXE
Press the [OPTN] button.
A set of thumbnails (TABs) appear on the lower part of the display screen.
Each Tab/Menu is activated by the Function key just below it.
Press the F6 Key corresponding to the right pointing arrow
Press [F3:Prob] to reveal the probability functions.

That is what you see

On the first screen above, the nPr menu corresponds to the permutations, while the nCr menu corresponds to the combinations.

To use them you need to enter n (the larger value), press the key corresponding to the calculation (F2 for nPr and F3 for nCr) and then press the smaller number (r). See screen below.

While the menus are displayed at the bottom of the screen you can use the other calculator keys to enter number, etc. As long as you do not press the Function Fx keys you wont activate them.

On the screen
  1. I set my calculator to the screen that is shown on the first screen capture
  2. I enter 15
  3. I press the F3 key: the Bold C is inserted after the number 15
  4. I type in 6
  5. To get the number of combinations that select 6 objects out of 15 ones (15C6) I press the [EXE] key.
  6. Result is 5005

When I try to divide numbers that would leave a remainder like 1 divided by 6 which should give me an answer like 0.16666666666 instead all it says for an answer is 1/6. it does say in the manual to input...


Hello,
To convert from fractions to decimals, and from decimals to fractions use the [S<-->D] key. If you want your decimal results to have a fixed number of decimal places press [SHIFT][SETUP][6:Fix]. Screen shows Fix 0~9. Enter the number of decimal places exemple 3.
Dans ce cas 1/6 is displayes ase 0.167.
Hope it helps.
