TI-Nspire CX CAS overview

[@Matheeha]

I just bought one for my SAT ... I am really amazed to know that it can do pretty much "EVERYTHIN" N obviously waaay better than our normal calc !!! Thank you for ur demonstration .. Was really helpful :-D

[@AnarchologyORG]

covenantbird, thank you very much for doing this tutorial. All of the others I've seen have been stupid people unboxing with no explanation of the functions. This sold me on the calculator! Thanks again!

[@chadkritzasteam4723]

I got this calculator yesterday for my Algebra class and I was overwhelmed with all the options (where to begin??) but your video helped me out with the basics. Just wanted to say thanks for that!

[@maxtreck]

You have no idea how much you helped me out

[@covenantbird]

I would recommend the TI-Nspire CX CAS. It is permitted on the AB or BC exam and you will enjoy having it around for any future math class as well.

[@covenantbird]

Absolutely. In fact, there are a goodly number of features that makes it a great tool for learning and exploring geometry.

[@covenantbird]

Most certainly. I have enjoyed using it AP Calculus for many years. There are a number of files on TI's website (and mine) for learning and doing calculus

[@Joaquin54]

Great teaching manual for a fabulous calculator. Thanks

[@covenantbird]

Yes, and it is called Press-to-Test (PTT) mode. Some people put their Nspire CAS into PTT, which disables some CAS functionality in the default setting, e.g. solve( ), however it is handy to have the cord and another handheld OR the software (or the free Computer Link software) in order to get out of Press-to-Test.

[@covenantbird]

Great observation. Thanks for the correction. I wonder how difficult that would be for me to correct. Perhaps I could make a pop up comment box.

[@covenantbird]

I used the TI-89 in my pre-calc and calc class for 10 years, but when the TI-Nspire came out 4 years ago or so, I've been using that ever since. There are so many reasons why I would recommend, but space does not allow. A summary the reasons can be found on my blog. Also I highly recommend posting this question with to TI-Nspire Google Group to get a response from Statistics teachers as well. Links to these can be found from my channel site.

[@Chrix1996]

How can i get the calculator to output π/4 instead of 0.785398 when doing arctan(1)? However this is on the TI-Nspire CX (without the CAS)

[@covenantbird]

1. You should probably get what your teacher recommends. 2. I wholeheartedly recommend CAS in Algebra 1. It is quite well suited for Alg 1 & 2. Being able to solve equations is a great tool for exploring, discover, as well as remediation and checking your work.

[@sugardeep]

Does this calculator has CTRL F function. If not what is the best way to search a sentence in a note.

[@BrooklynRose386]

I just bought this for college, so excited

[@alexgwada971]

thanks for the quick response .I think cas is only about software and not hardware so is it possible i can download some kind of CAS application for my Casio FX-9860 GII ?

[@NotSoProTactics]

Which one would be better for calculus ab, this one or the regular cx one

[@noah10105]

Is it a big stretch from a TI-83 Plus? I just got down all the statistic operations with lists and all that fun stuff, so i don't wanna have to relearn it all.

[@zowlyfon]

It it possible to put this in a test reset mode like the normal cx aswell as disabling the cas. The exam boards in the uk don't allow a cas.

[@KurtnTech]

I'm concerned that the trig functions are two clicks away... I am in Engineering at University and I probably use those functions literally dozens and dozens of times each day. Sometimes one algebraic expression will have 10-15 trig functions... Is there a way to shortcut the trig functions to the keyboard?

[@bobferguson4881]

Is this calculator relatively easy to get the hang of quickly? It seems as though it is pretty simple, so long as you don't delve into anything too complicated. Some features that I am really wanting to see in this calculator would be changing equations into other forms (y=mx+b , Ax+By=C. , etc.), getting the main info (slope, y value, x value) directly from putting in the equation, clear functional notation capabilities (being able to input a question written directly from a text book Ex: 28 x 8^6, 917,000,000,000).

[@covenantbird]

The first question may be best directed at 1-800-TI-CARES (if you are in the U.S.). I would say, use what you have. You've got the package license, then use it. Some tips about graphing on a limited domain can be view on a youtube video called "TI-Nspire Graph Inverse limit domain x=" Use the vertical bar | , such that.

[@thorshammer10129]

Does this do standard diviation and IQR? I want to know if i should buy this now as a 9th grader to use for high school and furture job?

[@petiee76]

Hi, I'm using this calculator for my Maths C assignment. Can you take a screenshot on the calculator and copy it over to a laptop?

[@covenantbird]

Petie E Yes. If you don't have the software that comes with the purchase of a new Nspire, you can use the free TI-Nspire Computer Link Software to get screen captures. education.ti.com/en/us/products/computer_software/connectivity-software/ti-nspire-computer-link-software/features/features-summary

[@EInc1000]

Can I use the CAS in in Algebra 1 to do stuff like equations? Although I will use it for calculus and in college (if it isn't out of date). I heard it's not suited for Algebra 1 or 2 and that I should get the one without CAS.

[@layzer6421]

Hi! I'd like to ask if this calculator has the Greek alphabet integrated in its charset palette. It seems very difficult to find an answer on that online. Congratulations for your video, it offers a ton of useful and interesting information!

[@covenantbird]

Thanks. Yes, you may have even noticed the Greek letter beta above the catalog (book) button. The Greek alphabet can be found by pressing ctrl catalog or you'll see the same symbol options by pressing catalog and choosing the number for the symbols. (On the TI-Nspire CAS it is option 4.)

[@finalbossd]

Would you recommend the TI-Nspire CX CAS for AP Statistics, AP chemistry, AP Physics, AP Econ, and

[@covenantbird]

Yes... and PSAT, SAT, AP Calc ...

[@Giodes921]

Hello, I have just a quick question: how can I connect the calculator to the PC? Is it possible to download some programs on my PC and then transfer them on the calculator? Thanks.

[@covenantbird]

1. You can use the TI-Nspire Computer Link software education.ti.com/en/us/products/computer_software/connectivity-software/ti-nspire-computer-link-software/features/features-summary 2. When you buy a new TI-Nspire it comes with the TI-Nspire Student software. You could also use that to transfer programs.

[@Giodes921]

thanks

[@BobDaBee]

Even for a 12 Year old video it’s still very good and helpful, thank you

[@williammcbride4560]

Does anybody know where i can buy a jump lead. to get this piece out of kiddy test mode?

[@latuernich]

Which calculator would you recommend for higher statistics functions like multiple regressions, ANOVA, tesing (Chi for example) and so on? Thanks for the video...

[@MunchkinMayham]

How can you lock the programs menu? (I must have it in order to take a final)

[@2012daffyduck]

at 1:20, does he say "escape at the upper *right* hand corner" ? , ah.. isn't that the left side?

[@Foxxxxx96]

hey! quick question, whats the difference between the Cx and Cx CAS, i'm guessing its just the CAS but i have no idea what that does... plz help

[@niccomaker]

Next year I might take AP statistics and analysis and the year after that I am taking AP Calculus. Would you recommend that I purchase this calculator? Some say that the TI-89 is better. Which do you prefer and recommend and why? Thanks

[@CarleyCatalano]

Maybe I should re word this.. My software that came with the CAS does not work with my Mac. Is it just my computer or is the CAS software not compatible with the new Mac system?

[@EasyTech15]

Great overview! Nicely done!

[@austininflorida]

In what ways is this better than something like the HP Prime? I am probably going into computer engineering.

[@covenantbird]

Both TI-Nspire CX and TI-Nspire CX CAS have all the same statistics functionality. Where you will noticed the biggest difference is on a Calculator page (or Scratchpad) when you press MENU > Algebra or Calculus.

[@MaryUkraine]

Can anyone tell my how it is better to install CAS: using my package license number or order (multi using) one. And, second, how to set the range or domain of graphs. Thanks.

[@b1onicviirus]

Is there a way of putting this CAS system into the TI-nspire CX?

[@DanielAbdelsamed]

B1oNiC_Viirus in theory you could code your own. But there is no easy way to do it.

[@covenantbird]

If you don't have CAS, I recommend Steve Arnold's resources compasstech.com.au/TNSINTRO/TI-NspireCD/Start_Here.html like TI-Nspire 2.0: Meaningful Algebra and his Polynomial Toolkit.

[@covenantbird]

I hear you. When I teach summer workshops where the teachers get a TI-Nspire CX or TI-Nspire CX CAS with the cost of the professional development, I try to encourage them to choose CAS (or at least know that it exists). So many times I've heard, "I would have picked CAS if I knew what it could do for me and my teaching." For those interested in summer workshops, I have info on my website or TI's website.

[@kkwalshiee]

what is better: ti-nspire cx handheld or ti-nspire cx cas? which one is allowed in more exams??

[@silverreyes7912]

Thinking of buying one.. currently in cal II integrals.. ive been using the Ti-83 and can do everything i need on there, however i heard this is good for linear algebra and vector calculus which i will be taking..I just like how the format for inputting math equations are.. everyone in my cal class has this or the ti-84.. only thing is most of the students have a hard time doing the math problems by hand and i dont, because since i been using the old Ti-83, my algebra is superb.. i just hope i dont get lazy and depend to much on this computer to do all the work for me.. Do you find yourself or students relying too much on these computers to where they have a difficult time in doing a problem like finding the volume on a solid using disk, washer or shell methods?

[@covenantbird]

Silver Reyes Yes, it is a delightful tool for linear algebra and all levels of calculus and on. Students still need to know the calculus for the set up. Back in the day we would use a table of integrals to solve the difficult ones. Now we can explore and do more mathematics because it can get done more efficiently.

[@silverreyes7912]

Yeah that is true .. I've decided to buy one and it is now currently in transit. Show be arriving at my house sometime today . Thanks on the feedback and for the video .

[@FRTovar95]

Can this calculator view images?

[@covenantbird]

If you use the software (that comes with the Nspire when you buy it new), you can insert images.

[@duendemental]

Hi, everyone. Could someone help me? I've bought a TI Nspire CX CAS and I'm trying to recharge it but it won't fully recharge. It only recharges til 75%. Does anyone know why? Thanx and great overview btw

[@CarleyCatalano]

Anyone have trouble with the software Ina Mac? Have they not made it compatible with the new Mac system?

[@TheMrFrontera]

Hey mr bird, can you direct me to somewhere where i can learn how to use the Nspire CX CAS to do more complicated mathematics, such as linear algebra and differenttial equations. Also where can i find useful apps/tutorials for use in chemistry?

[@covenantbird]

There is a TI-Nspire Google Group. Just today someone mentioned a book (electronic book) called "Using CAS Features Like a Champion" on the TI-Nspire CAS. On the TI-Nspire Group Website, under tns files, you can find a number of Calculus activities that I designed so that students are better equipped to use their TI-Nspire CAS. For differential equations I would especially recommend "Infestation to Extermination." Chemistry activities can be found through TI's website education.ti.com I highly recommend the periodic table available on the Nspire group website.

[@jakkirose6436]

This may seem like a silly question, but I really need to know because I'm having trouble with this on my current calculator. When you plug in multiple equations into the graphing screen, will the Nspire show the various functions in different colors? Let's say I have entries in Y1, Y2, and Y3. Will the calculator produce 3 different colors for the graphs? I have other questions about the Nspire but the comments page doesn't have enough room for them haha.

[@covenantbird]

+Jakki Rose I recommend you join the Nspire Google Group (you can Google search for it) and ask all your questions. Yes, the TI-Nspire CX will automatically show the graphs in different colors. Instead of using Y1, the Nspire's default is to use f1(x), f2(x), ...

[@jakkirose6436]

+covenantbird Awesome!! Thank you so much!! I'm a Chem major and I need a new calculator. I'm doing my research for them and im debating between a few different ones. So I'll check out the site you told me about =)

[@civedm]

Got my nSpire CX CAS and love it. My only complaint is the protective cover.When you have the cover on the back of the calculator, the calculator rattles around while using it. It sucks. Makes a 150 dollar calculator feel like dollar store calculator when using it. I have to shove a paper towel between the two to keep that from happening.

[@lucabrancatelli3063]

hi, someone can tell me how to use costant in linsolve? when i try to usa a costant the calculator give me an error: variables not declared thanks

[@GeertDelmulle]

And why exactly does a trackpad vs. a touch screen make a difference for being allowed on exams, or not?

[@henryreyes3604]

Geert Delmulle It's most likely one of those rules that people find loop holes in them. It probably just prohibits touch screen, but people where like "but you didn't prohibit track pad hehe"

[@Marrakchino]

i bought one this week, but i didn't find a battery ... is it normal ?

[@Kekuakahilikelii]

whats the difference between cx and the cx cas my cx cas

[@DAcanyousaymreyes]

Would you say this would be allowed in classes such as calculus ? Does the inspire have apps for calculus ?

[@covenantbird]

In answer to the question about installing the software on the computer, the TI-Nspire student software is available at education.ti.com

[@EInc1000]

Awesome! Now I know I can use it. At first I thought CAS couldn't solve simple equations for some reason.

[@covenantbird]

@kkwalshiee The TI-Nspire CX CAS is better: It has more built in functionality that is a boon for mathematics and science exploration and discovery. For the teacher, I say "Get the CAS!" Good question about the exam. The CX CAS is permitted on the PSAT, SAT, and the AP exams. CX is allowed on those and the ACT and IB. Many state math tests do not permit CAS, but do permit the TI-Nspire CX. If you need to take the ACT, then borrow a friend's who got the TI-Nspire CX, while you enjoy CX all year.

[@covenantbird]

I agree that the TI-Nspire CAS does what full CAS (computer algebra system) does on a PC. Yes, it does symbolic calculation.

[@ghg789987]

Can this graph in 3-dimensions?

[@covenantbird]

Yes, on a Graphs page (not the Scratchpad) press Menu > View and choose 3D

[@christopherknox]

When referring to one of your favorite keys on the Nspire (what I know as the pipe), did you say "substet"? I was having a hard time understanding you. Thanks.

[@inexinferis7064]

"Such that"

[@gabrielmbarret]

Hello i would like to know if it's worth to buying this calculator for electrical engineering,. It's better than HP 50G? THANK U NICE VIDEO

[@covenantbird]

Yes, get it for electrical engineering. And put Formula Pro on it. This file is even available on TI's website. education.ti.com/en/us/activity/detail?id=3FBF71F8F16C4151B0FB004CBAB469E4 The TI-Nspire CX CAS is the best choice for studying engineering. For taking the Fundamentals of Engineering Exam I would recommend the TI-36xPro.

[@koolwater97]

Look up nlaunch cx. You can use that to load cas on the non-ti nspire cx

[@HaloHamstur]

Can i browse the internet with this thing?

[@aissac19r51]

Actually studying electronic eng. would you recommend this one, or the Voyage 200? (A lot of graphs, derivate, integration, equation systems etc.)

[@covenantbird]

Especially now that some friends have created FormulaPro education.ti.com/en/us/activity/detail?id=3FBF71F8F16C4151B0FB004CBAB469E4 there is no doubt that the TI-Nspire CX CAS is the best choice for studying electrical engineering.

[@LeandroTercette]

Hi all. Can this calculator run in RPN mode? Tks

[@covenantbird]

The TI-Nspire is designed to make the math you see on your paper look like the math you enter. However, yes there is a way to do RPN on the TI-Nspire. Check out this link for more details kzbin.info/www/bejne/iISli6etaJ2ml8k

[@alexisrodriguezmejia6622]

In your opinion what is best for a 11th grader taking the ACT and SAT, the Ti-NSPIRE CX or Ti-NSPIRE CX CAS?

[@covenantbird]

The TI-Nspire CX CAS can be used and is a delightful tool for AP exam and the PSAT and SAT. However, it is not permitted on the ACT or IB exams. The TI-Nspire CX is allowed on all of those. I do prefer teaching and learning with the CAS.

[@nonesta13]

does anyone know how to switch from radians to degrees and vice versa on this calculator so i can solve sin(60) the right way?

[@covenantbird]

1. I recommend keeping it set in radians and using the degree symbol. sin(60 degrees) = sqrt(3)/2. The degree symbol is found by pressing the pi button near the bottom left of the keypad. 2.(a) From the home screen press 5, 2 Document Settings and change the settings to degrees. Be sure to make it the default so that the Scratchpad is in degrees. (b) Or access Settings when you are in a document, from DOC. (c) Or click the gear in the upper right. 3. Regarding "vice versa," did you see that there is a little r near where the degree symbol is?

[@civedm]

(180/pi) to switch to degrees and (pi/180) to switch to radians....

Can this calculator solve : 1] Analyzing Function. 2] Exponential and logarithmic Relations and functions. 3]Trigonometric identities and equations. 4]Conic sections and parametric equations. ??? Pls reply!

[@covenantbird]

Yes, the TI-Nspire CAS can solve equations of all sorts. If you are asking can it graph and analyze functions, then the answer is yes. It can graph conics and parametric. It can analyze conics. There are also nice things you can do with tcollect & trig expand to work with trig identities. So my answer would be YES.

[@Matt-re4et]

I'm contemplating purchasing a ti-89 the Nspire CAS but this pretty much made up my mind.: )

[@covenantbird]

Matthew Coury TI-Nspire CX CAS is so much better: Color, speed, rechargeable battery, pretty print on input and output.

[@sammariofan]

Should everyone just get the CX cas instead of the base CX model?

[@itsoktobejey]

Depends on what you want to with it, I'm going to buy the non cas version because the other one isn't allowed at my final exam

[@covenantbird]

CAS = Computer Algebra System. It has some additional features beyond the TI-Nspire CX. On my blog (click covenantbird, click the link to my blog, then search Computer Algebra System) I wrote: "The opportunity to use mathematical technology empowers students to wonder 'what if' and then actually investigate it. I think this is particularly true for the TI-Nspire CAS (computer algebra system - for a comparison to the numeric Nspire check out this link)." [Link is live on my blog.]

I dont think this is aloud at the the university of Houston or community colleges around the area, last tried class that got me kicked out of college I couldn't use anything higher that TI84

[@covenantbird]

TI-Nspire CX CAS easily wins for many reasons: (1) speed of graphing, doing calculations, running programs, etc; (2) color when graphing functions, 3D, slopefields (again it has this functionality built in and does it much faster than the 89); (3) color in mathematical interactive Notes pages, etc; (4) Nspire CX graphs conics, (5) 'pretty print' on the input, not just the output... Check out my godly dominion blog for more details on why I use TI-Nspire instead of other things. I used the 89

s^4+3s^3+s^2+5s+10=0 Do you know how to solve this equation? My nspire can't solve it :(

[@covenantbird]

If you have the TI-Nspire CAS, you would get the two solutions by doing solve(s^4+3s^3+s^2+5s+10=0,s). With the numeric Nspire (it doesn't say CAS) you can do nsolve(s^4+3s^3+s^2+5s+10=0,s) and your get one of the solutions. I would recommend finding the solutions graphically. Graph f1(x)=x^4+3x^3+x^2+5x+10 and find the zeros using trace. Press enter at those locations and the values will stay there. Hover over the value and press + and you'll get more digits. With numeric solving you can get the other value if you provide a guess that is on the other sides of the value, e.g. nSolve(s^(4)+3*s^(3)+s^(2)+5*s+10=0,s=−10) gives the other value

[@andrewsebayjf]

just use synthetic substitution to solve that. It's an Algebra 2 concept, if your handy with Algebra 2 you should be fine.
