On my casio fx-82au plus calculator it won't

The capability of these calculators to handle irrational numbers in radical form is limited to square roots. Roots of index other than 2 are always displayed in their decimal representation.
If the calculator IO mode is set to MathIO, square roots will be displayed with the radical symbol. More complicated expressions with square roots might not be preserved and will be given as decimal numbers.

Hi there, I have a Casio fx-991ES, and my calculator doesn't seem to be converting decimals in surd form... i.e. 0.3354101966 was the last number I typed in that didn't work... That, in surd...

The calculator can't identify that this is a surd unless you input it as a surd, ie as 3/(4*sqrt(5))= when it will then show the equivalent form 3*sqrt(5)/20 (obtained by multiplying top and bottom by sqrt(5)) and you can swap between the two forms using the S<>D button. Even adding the next 4 decimal places (hidden) won't allow the calculator to identify the underlying surd as this is simply too complcated a calculation.

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

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.

How to find general anti-derivative Problems in Casio fx-115ES... I get the message syntax error, and also when the anti-derivative is bounded I get my answers in decimal form, i dont want decimal form......


I assume that by anti-derivative you mean the integral. I believe that you can only calculate definite integrals with this calculator. A definite integral requires that you specify the function e.g ln(x), the variable, x, the numerical value of the lower limit, 0.5 and the numerical value of the upper limit , say 2.
Try this: INT(sin(x),x, 0, pi/2)
This calculator can only give numerical values of definite integrals. If you want to perform symbolic calculations, you shoul look towards some other, more sophisticated Casios Casio ClassPad 330, or the TI Voyage200PLT, or the TI89Titanium. etc.

Hope it helps

The answer comes up as a fraction

this is in surd/math form,

to get to line form press Shift > Mode (setup) > 2:LineIO

this may be option 10 but you are essentially looking for something with the word line in it

if you are doing A-Level etc. you may wish to just press the S<>D button instead

hope i helped

I have a ti 83 plus calculator and when i type in say radical 50 i want it to give me 5 radical to not the decimal form how do i change this


Your TI83 calculator is a powerful machine but it does not do symbolic algebra. Results are always displayed in decimal form
(Did you notice that it does not have a %key.)

Some new (not very expensive) calculators can do that : Casio FX-300es, Casio FX-115es,Casio FX-991ms or es. These type of calculators are known as NATURAL DISPLAY, or WRITE VIEW (from Sharp).

Hope it helps.
