20 Most Recent Casio FX9750GII Graphic Calculator - Page 2 Questions & Answers

Can it differentiate functions? Yes it can. More specifically, it can evaluate the 1st and 2nd derivatives of a given function at a given point (Numerical differentiation). On any graphed function you can configure the calculator to display the first derivative. When tracing the curve, the 1st derivative is also shown at the trace point. For any function, not graphed

Hi Danny, is it correct battery. please check if it is good. leave it a half an hour wit case opening or heat it with 10-20 secs with hair dryer and try again with good battery, regards, nuwan

Create a list with the required dimension (n) In Run>Mat, Press OPTN > F1:List Using the keyboard , F3:Dim, and F1:List Type in n--->Dim List 1 (for example), Using the F4:Fill and F1:List tabs enter Fill(0, List 1) EXE

You can create two-element lists and store the results in them. Create a list L1 with dimension 2 Calculate the Polar coordinates of the point (1,1);: just an example The 1st element of List 1 is the radius, and the second element is the angle (in radians). Convert it to degrees if you wish. I won't do it. Now you must extract each element and store it in the r, and theta variables, [ALPHA][x^2] (r) and [ ALPHA] [^] (Theta) Extract radius and store in r. Extract angle and store in Theta. To store the rectangular coordinates (x,y) do the same as above. I will leave this pleasure to you. Note: I inserted screen captures from my calculator but I am not sure if the Parser will accept them. If it does not I will create an image file and insert it as media.

In Run>Mat screen (Menu 1) Press the OPTN key. Press F4:CALC Press F6> Press F4:logab Alternatively, In Run >Mat press [SHIFT] 4 to enter the CATALOG. Press L to go to letter L in catalog, then scroll from there until you reach logab.

Use the USB cable. In the Link(ing) configuration set USB Read the manual for more details. Some software that is available is Screen Receiver by Casio

You can use the SHIFTED [^] key (Xroot) . Enter the index of the root (4, 5, 6, nth), press [SHIFT][^] then the radicand.You can also use the fact that nth-root is equivalent to a power (1/n)

The F-D key converts a displayed result from fraction to decimal and vice-versa. If in the polynomial expression a numerical coefficient is a fraction just enter it as a fraction, possibly enclosed in parentheses. If it is a decimal number just enter it as a decimal number. Converting it to a fraction is not going to generate any more precision in the result. You lose precision when you go from fraction to decimal, but you do not make a number more precise by converting it from a decimal representation to a fraction.

Tell me where the key (or Submenu TAB) is and I will tell you how to use it. Apparently you were living in TI Planet and now have moved to Casio Planet and you need to adjust to the jet lag brought about by the transition.In Run>Mat press [SHIFT][ MODE] to enter the (Setup).. On the 5th line: Derivative set the selection to ON.Press Menu then Graph. Enter a function, validate and press F6:Draw. Once graph is draw press the F1:trace key. A CROSS appears on the graph indicating the default starting position. At the bottom of the screen you see X=, Y=, and dY/dX= The last one is obviously the value of the derivative at the position of the cross. Move the cursor to another point to see the values X, Y, and dY/dX.You can also enter a value of X to find Y and dY/dX. Make sure the X-value you enter is in the interval between Xmin and Xmax, the window limits.

If the table contains experimental (statistical) data that you gathered and put in a table on the calculator, then I am sorry to say that if table is deleted there is no way to get the data back. You will have to renter it.However if it is a table connected to a function you graphed then the table can be regenerated: Type in the function anew, press the table function key, then graph it.

The derivative of sin(cos(x)) dx is cos(cos(x))-sin(x). Unfortunately the fx-9850GII doesn't do symbolic differentiation so you'll have to get this result some other way. I cheated and used a calculator from another manufacturer, one that does do symbolic differentiation.

Here how it is done. Don't mind the calculator it was done on. On your you may have systems of up to 3 linear equations.Follow the screen captures. I do not think any additional comments are warranted. Pressing the F1 key (REPT)-- see last screen capture--allows the user to repeat the solution with the same coefficients or other ones (different system)

We need verbs (actions) in your questions and interrogative pronouns too. Anyway, to have a numerical result displayed in scientific format, you must set the display to scientific. You must specify the number of decimal digits to keep. To set the display format, open the Run>Mat screen. Press [SHIFT][Menu] to open (Setup). Scroll Up to reach the line Display, press [F2] (Sci), type in the number of decimal digits, press EXE. See the screen captures below.

Use the button marked [a b/c].Type the integer part, press the button [a b/c], enter the numerator, press [a b/c], enter the denominator then the EXE key.

What were you doing ( the command you were executing) just before you get the error?

To access the absolute value command, got to Run/Mat screen and press OPTN. Press F6> the F4:NUM, then F1:AbsIn the Y= entry screen, press OPTN, then F5:Num, F1:Abs. enclose the argument of the function inside parentheses.Here are two screen captures to show how it is done.

The calculator can calculate numerical values of derivatives of functions (at a given point). It does not have a Computer Algebra System so what you want to do cannot be done. You should look for a Casio calculator with a CAS, such as the ClassPad, the FX_Algebra 2 or the FX 9860G. Sorry.

The solution set of a linear inequality in two variables (x,y) is one half of the Cartesian plane. The half-plane may or may not contain the boundary line defined by the = sign. Thus it is expected that the calculator shades the relevant half-plane. If you are dealing with nonlinear inequalities the calculator shades inside or outside the curve. When drawing multiple inequalities the Casio offers you the possibility to shade the regions where ALL conditions (ALL inequalities) are simultaneously satisfied. The other option is OR.If you are not interested in the shading do not draw inequalities, draw equations (with =).
