Will I be able to solve systems with more than three variables? I need a calculator that can solve matrices but it can't be a graphing calculator

Check CANON F-792SGA http://www.amazon.com/dp/B009FFPEH0/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=UV9EGCN66QW&coliid=I6EJNTONVYL9Y

You can't make Y or T. An 8 could double as a B and it does have an A. So basically, no you can't make BY APPT.

The calculator uses both lines typically the top holds aforementioned as the second line considers changes within the mathematical expression. Regarding correlation analyses or even regression, the use of one or two variables for a standard error of estimate I was unable to locate any restrictions within the display. With my limited experience with the calculator, I never ran into an issue based upon display limitations.

Yes. To get to complex calculation mode: Mode -&gt; 2:CMPLX To change to polar or rectangular output: SETUP -&gt; Down -&gt; 3:CMPLX -&gt; (1:a+bi or 2:r&lt;theta) Or, to change radians or degrees: SETUP -&gt; (3:Deg or 4: Rad) To change polar to rectangular for a single output, you can pick: Shift+2 -&gt; (3:r&lt;theta or 4:a+bi) Note that this calculator can swap back and forth between exact mode and decimal mode very easily. Example: sqrt(3)/3 + sqrt(3)/2i Press S&lt;&gt;D button: 0.57735+0.866025i I used to use my TI-89 for everything, until I read through the manual for this thing and realized that it's far quicker to get to things I use on a daily basis with this thing. AND it gives it to me with exact notation more often than not, a feature that my TI-89 just wasn't very good at. And all of the symbols you need are in button form, instead of somewhere deep in a catalog. Notice the Log(base)(value) button. I haven't seen a single calculator other than this one which has that button, and I use that all the friggin' time. It was certainly worth a try. If my time is worth $30 an hour as an engineer, it has already saved me hundreds of dollars in time compared to my TI-89.

Yes. The 35s can store many equations. There is 30 kB of user memory available. The problem is that once the equations are stored, there is no way to backup memory to a computer or disk storage. You will need to write the equations down on paper and key them in again if the memory is lost or reset.

Haven't used the HP. The Nspire cx CAS is very nice. I have no complaints. The user interface is simple enough to use for quick computation and capable enough to do a lot more. I have the TI Software but haven't tried to write my own programs yet, but this software will make it quite nice should I need to. I'm guessing you'll be working with complex numbers, matrices, linear algebra stuff and the Nspire is a champ for all of those and more. By the way, make sure you get the CAS version.

They have 6 systems. I think system 5 or 6 is the one you might need. Good luck.

I really don't know. I have always used 4 and never thought about using 2. I don't know why you could use just 2 though.

Straight out of the box, no, but you can use the integer zeros from the graph, or integer solutions from equation solver, to find the factors. Also, as AL mentioned, there are CAS programs you can add to it.

I am sorry i can't help , since I have never tried to use this in an adding machine/calculator. Good Luck

Yes this calculator have a capability to solve the complex equations and you can check the answers to verify your work

Diagonals work fine for me. Sorry I don't know why it's not working for you.

It's not a graphical calculator. So I would say no. You may want to check out TI-84.

I have not taken statistics, although I have taken a LOT of advanced Calculus. This calculator honestly does EVERYTHING. It has a spreadsheet, graph, it will do derivatives, integrations, it analyzes matrices, so yes, I believe it will do anything you need it to do in a statistics course. It's spreadsheet is kind of like an excel sheet and will analyze a set of data using various equations and so forth. Yes, I WOULD recommend it for just about ANY math course.

If you wanted to run all 3 at the same time off this unit it probably won't work, but if you understand your constraints and only operate 1 at a time you shouldn't have a problem. It may take you a few days to tune in your settings, so be prepared for that. Once you establish your settings you will be golden.

Indeed, and can simplify into decimals for you. You can even easily do formulas where you stack fractions.

No. It will solve polynomials of degree 2 to 6 (including complex roots), but will not factorise them. You can add unofficial programs that will achieve this, but in its standard form, this is a non-CAS (Computer Algebra System) calculator.
