Question about Casio FX-9750GPlus Calculator

1 Answer

On the CASIO Fx-9860GII, how does one do time derivatives ( i.e. (dx/dt or dy/dt)) for use with parametric functions? I am attempting to find the arc length of a parametric function.

How does one do derivatives/integrals with respect to time on the CASIO fx-9860GII?

To calculate the arc length of a curve you need the derivatives as functions of a variable not the derivatives at one point. If I were you I would read the manual for more complete information. Maybe if you wrote a program that does that.

SOURCE: Does anyone know how to calculate derivatives

hello,
The calculator will calculate the derivative at a point. It will not give you the formula for the derivative, just the derivative at the point you choose.
Sorry, it can ONLY do NUMERICAL differentiations and integrations.

SOURCE: how to use trig function keys on my casio fx-300ES

Hello,
You have 3 keys for the main trigonometric functions: [SIN], [COS] and [TAN]
To use them correctly you must set the angle unit to the one your problem calls for.
Press [SIFT][MODE] [3:Deg] for degree, [4:Rad] for radian, [5:Grad] for grad. Dependig on angle unit chosen a small D, R, or G appears on the top of the screen.

If you need the inverse trigonometric functions arcsine, arccosine, arctangent, you access them by first pressing the [SHIFT] key
Thus
arcsine [SHIFT][SIN] (sin^-1)
arcosine [SHIFT][COS] (cos^-1)
arctangent [SHIFT][TAN] (tan^-1)

The syntax for the function is
[SIN] # [ ) ] [=]; [SIN] 30 [ ) ] [=] gives 0.5
[COS] # [ ) ] [=] [COS] 19 [ ) ] [=] gives 0.945518576

Note: if the argument of the functions are numbers, the right parenthesis is not necessary. But if the argument is an expression (with various operations) better put the parenthesis to make sure the calculator is performing as one wants it to.

By the way, there are no keys, or key combinations to calculate cotangent, cosecant, and secant, but you can use the definitions:

cotangent (x) = 1/tan(x) Do not confuse it with tan^-1
cosecant(x) = 1/sin(x) Do not confuse it with sin^-1
secant(x) = 1/cos(x) Do not confuse it with cos^-1

Hope it helps.

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.

You cannot. The calculator does not have the Natural Display (math display) feature. I have heard that you can flash it with the OS of an FX-9860GII. At your own risk.

Can the casio fx9750gplus calculator show differentiation/integration etc. for example differentiate 5x^3 and have it show 15x^2?


Sorry to disappoint you but the Casio FX-9750Gplus does not handle symbolic calculations. It does not have a Computer Algebra System or CAS. It can however calculate the numerical integration of a function between two limits, as well as the first and second derivatives of a function at a given point.

  1. To access the numerical integration and differentiation,
  2. Press the Menu button.
  3. Highlight the RUN icon and press [ENTER/EXE]
  4. Press [OPTN][F4:CALC]. Then
  • Press [F2:d/dx] for first derivative
  • Press [F3:d^2/dx^2 for second derivative,
  • or [F4:integral]

How to use graphing calculator?


The casio FX-300Ms calculator cannot do graphs. To tell you how to use a graphing calculator TO DRAW GRAPHS we need to know the exact brand and model number of the calculator.

  1. Most graphing calculators basically function the same way.
  2. You select the graph type (function, polar,parametric, sequence, 3D, wire mesh, slope field, etc.)
  3. You enter the algebraic form of the function you want to draw.
  4. You press a button or menu to GRAPH
  5. The graph is drawn.
  6. If you want to see a particular part of the graph, you use a ZOOM function, or you enter values for the WINDOW dimensions.
  7. Most graphing calculators have a TRACE function that allow you to follow the curve you have drawn to read off values of coordinate points.
  8. You can also use the calculator to find zeros roots) of functions, calculate derivatives at some chosen points or calculate the area "under the curve", find the minimum and maximum of a function.
In addition to its graphing capabilities, a graphing calculator can be used as a scientific calculator. Sometimes it can also do statistical and financial calculations, matrices, list manipulations, operations on complex numbers, text editing,, creating programs etc.

Can the TI 84 calculate second derivatives?


Hello,
I am sorry to disappoint you, the nDeriv ( function can only calculate numerical derivatives of an expression at a point. The dy/dx can do the same thing (calculate the first derivative) at one point on a displayed graph. It can be activated for graphs by pressing TRACE, then [2nd][CALC][6:dy/dx]. If you need the derivative at more than one point you have to press [2nd][CAL] [6:dy/dx] again.

What I said above concerns the native abilities of the calculator. There may be applications you can install to allow computation of 2nd derivatives. look for them on the TI site, or the archive section of ticalc.org. Try deriv

Hope it helps.
