In Run>Mat press the OPTN key, Then F6:> to move to the next page of options. You will see the ANGL tab as on the screen capture (above F5 key. Press F5. You will see what follows. Type in 50, press the F4 key, 25 then F4, 23 then F4. Press EXE. you get the result in decimal degrees as on the screen capture. To convert from DMS to D.D, or from D.D to DMS, vice-versa, press the F5 key

Checking the batteries is the first thing one should try. It is possible that for some reason the screen may be too dim. Reset the calculator by pressing the button on the back. The screen should show the menus. To adjust the contrast you must press the E key (no need to press the ALPHA key for that.) then press F1 to access the contrast setting feature. Press the Right pointing arrow to increase the contrast.

I believe you must rethink the design of your program If you have several inputs that lead to a single result you want to keep for further calculations, enter the inputs, calculate your result and store in a variable. The intermediate variables can be set to zero (by precaution) and reused. Use functions, and subroutines. Usually, in well designed programs, the scope of a variable defined inside a function or subroutine is local :It can't collide with the same name used globally (global scope). If a variable is no longer needed destroy it and reuse it.

x^2 squares the value (multiplies by itself), x^-1 inverts it (divides it into one), x! calculates the factorial, and square root calculates the square root.

I had the same problem too. I just bought it and I was trying to turn it on but it wouldn't though the manual said that it was supposed to automatically when the tab was pulled out. Good news: the Reset button on the back works. I pushed it for some time with the end of a toothpick and it worked.

hope it helps.

To draw graphs.

1. Turn calculator ON (isn't that obvious?)
2. If you see no icons, press [MENU]
3. Use arrow to move focus on GRAPH and press [EXE]
4. By default, the graph type is Y=
5. Enter your equation on line Y1=, use the [X,theta,T] key to enter the X-variable
6. Press [EXE] when finished entering a function.
7. Enter other functions if you want.
8. When done, press [F6:Draw].
9. If you do not see a big portion of the curve you can press [SHIFT] [F2:Zoom] and select [F5:Auto]

I am enclosing screen captures. The screens you see may not look exactly as on the FX-9750G, but all menu commands you have to execute are accessed by the same key sequences.






This last one is obtained with the Zoom: Auto

There is nothing mysterious about it. Wittingly or not, you switched the window limits. Examples Xmin=6.3, Xmax=-6.3 Ymin=3, Ymax=-3 or some other combinations. Here is the 1st case (Xmin=6.3, Xmax=-6.3, Ymin=-3, Ymax=3). The traced point has positive x Complete switch. The graph looks correct but as you can see the traced point has positive x, and negative y. I did not think the calculator would be that tolerant.

I am not sure what you mean by a 3X4 system. I know system of n equations in n unknowns. It is written in the form of an nXn matrix A multiplied on the right by an n vector (X), and n vector B holding the right hand sides (constant values)[A]*[X]=[B]In the EQUA mode, the calculator offers you a template to enter the numerical coefficients in the horizontal sequence a11, a12, ... a1n, B1Fill the first line, then the second line, etc.Once you finish entering the coefficients and the constant terms press F1 (SOLV) to launch the search for the solution. The result is displayed as a vector. (vertical vector).

Hello,
Here is a link to all chapters in the manual.
Hope it helps.

1. Press [2nd][LN] to activate the exponential function.
2. Type in the exponent 0.2
3. Press [EXE]
   

[2nd][LN]0.2[EXE] Result is 1.221452758

DO NOT PRESS [^] : this is the source of the syntax error.
You can put the exponent in parentheses.
If exponent is negative, press the change sign key (-) right after the e appears on screen.

[2nd][LN][(-)]0.2 [EXE] gives 0.8187307531

In Run screen, press OPTN>F6>F5 (Angl). The Degree/Minute/Second key is the TAB above the F4 Key.To use the key for example to type in 58 deg 33 minutes, 27 seconds type in 58, press F4, type in 33, press F4, type in 27 then F4. Press EXE. The screen displays 58.5575.A new tab appears above F5. Press it to convert displayed result to DMS

Press the Menu key. Use Arrows to reach Graph or press the digit key correspondin to it (maybe 4).In the Y= entry screen type in [X,Theta,n] then + then 3. Press EXE.Enter the second function (-)X+9 folowed by EXE.Press the Function key F6 under the Draw Tab..

Press the Menu key. Use arrows to highlight the Graph utility. The function input screen opens so that you can type in the function Y1=-X^2+5X-3You can play with the line style, or other features.Press ENTER EXE to validate. Then Press the Function key to activate the Draw tab.

By default there ane no programs installed. If you want to create some program, you press the key under the [NEW] tab and start typing.If you you had transferred some programs from your computer to the calculator, you would have found them listed under the PRGM mnenu.Here is the link to the software ressources at casio education.
