How do you make the calculator give the answers in surd form?

Also can you do integration and diffferentiation on it??

Hello there!

There is a page, on the manual, I don't remember that tell how to change that!

or consult on tech forum Casio, for another hint.

Good Luck

Change the output display to MathIO. You may be able to display square roots only: so no cube roots, nor fourth...

Press the Shift/Mode key and set the Input/Output to MathIO.

Even that will not guarantee that the display will be in root form. Only square roots are possible.

Looks like <Shift><Mode> <down arrow> <1>

Give it a shot. I have attached the manual.

Good luck.

The Casios FX-115 ES , FX-115 ES PLus, FX-991 ES, FX-991 ES Plus C can perfom numerical differentiation at a point, and numerical integration between two given limits.

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.

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.

Hello,

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

Hello,

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 i**t 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.
