Question about Texas Instruments TI-30XA Calculator

Ad

It's an algebraic calculator that evaluates higher order functions like X, / before +, -.

So you have to make sure you input properly.

Your example:

1-61+2= will give you top line result.

Then enter

/

(

5-6

)

=

You need the brackets for the divisor or it will divide the top line result by 5 and then subtract 6 from that result, which is not what you are trying to do!

Sorry, this calculator can only manipulate numerical values, not algebraic symbols. It does not a have a CAS (Computer Algebra System).

Here is screen capture of the calculation, performed on TINspire with TI 84 plus keyboard.To type in the imaginary unit use key sequence [2nd][dot], do not use [ALPHA][X^2] for the letter I.

The calculator itself does not have a computer algebra system and therefore cannot handle algebraic expressions.

I am afraid I do not completely understand what you want. This calculator does not have a Computer Algebra System or CAS. So the results of all calculations will be displayed as decimal numbers, and that includes the square and other roots that are irrational numbers (square root of 2, 3, 5 7, etc.)

You cannot manipulate radicals on this calculator, whether for small numbers or large numbers. Sorry.

the 89 is in my opinion not need/ approriate for a 10th grade algebra class, or worth the extra money.

for example the 84 wont output variables it must output a number

so your son may be doing factoring, if he inserts (x^2+2x+1) the 89 will allow him to enter it and factor it as (x+1)(x+1) or (x+1)^2 the 84 will not.

the 84 will do pleanty as far as graphing, finding zeros,plotting, calculations, and should get him any answer that he seeks so long that he knows how to use the 84. It just wont give him the intermediate steps the the 89 is able to give.

hope this helps

You cannot do it with this calculator. It does not have a Computer Algebra System (CAS). Try a TI89 Titanium, a TI 92PLUS, a TI 200PLT or a TI-Nspire CAS.

However, they may exist other programs on education.ti.com or ticalc.org. Search these sites and you may be lucky.

Well, to answer part of your question, yes... the TI-89 does factor like this. it is inputted like this:

factor(6*x^2+11*x+4,x)

Check the catalog in the TI-84 (which is 2nd-zero) and look under F for factor()

factor(6*x^2+11*x+4,x)

Check the catalog in the TI-84 (which is 2nd-zero) and look under F for factor()

Please help me to find the answer for my problem with TI-84:

If I'd like to work with:**nDeriv(3X^3+2x^.5),X,1) **

then I press Enter button, the sreen shows Error...

Please help me to get the answer for this problem. Thank you very much!
