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: mode change

Hello,
Just so that we know what we are talking about. The natural display is the display mode in which fractions appear on two lines, radicals appear as radicals, log can be calculated in any base, etc. If that is what you understand by Natural Display, we are in agreement.
To set this mode, you turn calculator ON and press [SHIFT][MODE] (setup). The option is called MathIO, and it has the number 1.
Thus [SHIFT][MODE][1:MathIO].
Hope it helps.

SOURCE: how can i calculate probability distributions

Hello,
Not knowing what kind of probability calculations you want to perform, I can only show you how to access the distributions that this calculator has to offer.
After you enter your data and do the usual statistics, you press SHIFT STAT and select 7:Distr. You get acces to
1: P(
2:Q(
3:R( and
4: X to t, the variate.

See the exemples in the Appendix to the user's manual, in particular #059.

Hope it helps.

Only one button which is used for integration/differentiation is not responding


I am not sure what you mean. The key allows yous to calculate the definite integral of function which you enter on the command line. You must also enter the lower and upper limits. When used do differentiate, you must enter the function, and specify the point at which the first derivative is evaluated. Try the two features with simple functions to test whether the calculator is working.

How to calculate calculus problem by a scientific calculator fx-991ms


Hello,
If by calculus problem you mean derivatives of functions, integrals, extrema and such things, I am sorry to inform you that neither the Casio FX-300MS, nor the FX-991MS can handle them. The newer Casio calculator FX-991ES is capable of performing numerical differentiations and integrations. There also graphing calculators by Casio FX-9750G, FX-9860G as well as by Texas Instruments (TI 83 PLUS/TI84PLUS) that are reasonably performant in that area.

Hope it helps.

Hi I want to check which calculator is in best working condition. How to check it before buying?


Hello,
If you are looking for a casio calculator, go for the FX-991ES, or if you want to save some money the FX-115ES. It has less functions (integrals and derivatives).
While there are possible manufacturing defaults, probability is low. Most failures come from inconsiderate uses and careless handling by owners.
Hope it helps.
