    My MAT 103 professor decided yesterday (TWO DAYS BEFORE EXAM #3) that we needed a graphing calculator to complete this exam tomorrow (no, it wasn't mentioned in the syllabus or anything). This video series is an absolute GRADE SAVER right now. Thank you so much!!

    I have less than a month to get myself ready for a college algebra course, and realised, in addition to everything else I need to teach myself, I also need to feel confident with my new calculator before class starts. I'd figured out a few basics (very, very basic things, like on and off, use of the alpha and 2nd keys).
    This first video has given me a taste of its capabilities. I look forward to the rest of the series and feeling less overwhelmed by the TI-84 Plus CE. I'll be adding the book to my collection before classes start next month, for more in-depth information.

      Thank you for commenting back to me. I'm in the 2.4 section of the "using the ti-84 plus" book. This book is very clear and easy to use. I recommend people who want take advantage of the ti calculator. I'm only in chapter 2 and I've learned more about using the calculator in this book than my whole life time. I'm 46 years old.
      This book is so addicting. I can't seem to put it down. Every page has some great examples to do. If I had to compare this book to would be like a Final Fantasy XIII strategy guide. I love playing Final Fantasy XIII and with the strategy guide. The game is even greater to play, finding secret treasures and weapons.
      So this "using the ti-84 plus" to me is a strategy guide book for calculator and all it's powerful apps. That's one of the reason I can think of.
      I read a little bit about the ti-basic too. I can't wait to order your "Programming the TI-83 Plus/TI-84 Plus". It' going to be another addicted book to have. I'm ordering 2 copies again for me and my grand daughter. To just have a complete collections I'm going to get the using ti-84 plus 1st edition from 2012. It's going to be awesome.
      Just want to say thank you Christopher R. Mitchell for these great books.
      I hope whoever loves using the ti calculator will get these books. It is a priceless knowledge to have. I can't wait to get those other two books.
      I do have one question. I upgraded to the 5.2.2 os and I can't seem to be able to drag any of the games into my calculator using the ti connect. But it's a simple taste that I can look up. I just wonder if it's an issue or it's just me not knowing what I'm doing.
      Thanks again.

    • @KermMartian
      @KermMartian  8 ปีที่แล้ว +2

      Your calculator can't do that on the homescreen. However, there's a Solver in the [MATH] menu that can find the value of X given such an equation; the book ("Using the TI-84 Plus") explains how to use it. However, surely you can do that by hand, by multiplying both sides by 67.3 (38.46x = 7*67.3), then dividing both sides by 38.46 (x = 7*67.3/38.46). It's very simple algebra. :)

    • @KermMartian
      @KermMartian  8 ปีที่แล้ว +2

      No, unfortunately. The French version of this calculator, the TI-83 Premium CE, has an exact math engine that will do things like simplify radicals for you. Because of pressure from exam boards (eg, the SAT board) and teachers in the US, the TI-84 Plus CE has no such feature built-in. However, hopefully one of Cemetech's members will make a program to replicate this functionality soon. You can check out what's already available at www.cemetech.net/programs/index.php?mode=folder&path=/84pce/basic/math .

    I'm trying to generate a random number. I had math and then I scroll to the right "PROB" , then I hit 5 "randNorm" . But every time I hit 5 I get a weird message, it says lower upper and paste? What does that mean?

    • @KermMartian
      @KermMartian  7 ปีที่แล้ว +1

      It's asking you for the upper and lower bounds of the random number to generate. You can disable these so-called "Stats Wizards" in the [MODE] menu if you want. If you're trying to generate either a random integer or a random floating-point number, you should also look at rand and randInt.

      The TI-84 Plus CE can't solve algebraic expressions like the on the homescreen. However, if you go to the [MATH] -> Solver... tool, you can enter 2X+20 as one side of the equation using the [XT0n] key, 14 on the other side, and press [ALPHA][ENTER] to solve.

    • @KermMartian
      @KermMartian  8 ปีที่แล้ว +1

      This is an unfortunate but logical result. The exponent sign has higher priority, so it's applying the exponent first (giving you 1^4 = 1 or 5^4 = 625), then applying the negative sign. You can solve this with parentheses: (-1)^4 or (-5)^4. Good luck!

      It sounds like your ON button might be faulty. To double-check, hit the little RESET button on the back with the tip of a pen, and see if that fixes it. If not, call 1 800 TI-CARES and see if they'll replace it under warranty.

      Marwa Katir To do this you have to enable MathPrint. To do this hit the mode key, and the first line should have two options: MathPrint, and Classic. Select MathPrint. If these options don't show up, you need to update your operating system. You can look up how to do this on youtube, or you can ask your math teacher to do it for you, most know how to...

    • @KermMartian

      The TI-84 Plus CE is indeed still TI's most recent model. It will do statistics, probability, time series, regression, numerical calculus tasks like definite integrals and derivatives at a point, and numerical linear algebra. It does not have a CAS (Computer Algebra System), so it cannot do symbolic indefinite integrals and symbolic derivatives, and other symbolic tasks. I hope this helps!

      Thank you KermMartian. Excellent analysis. Does the linear regression, matrices, probablity, statistics, linear algebra, uni-variable and multi-variable calculus, time series, functions all come native out of the box or do I have to download these as plugins? I am mostly using it for Mathematics for Economists and Financial Analysts as well as Data Scientists and Policy Analysts. Data Science as an example is heavy probability, regression and statistics. I am embarking on MA in Econ - using Math for Economists and Econometrics and Financial Economics as well as Data Science using "r". Is the color version worth purchasing instead of monochromatic?

    • @KermMartian
      @KermMartian  7 ปีที่แล้ว +1

      All of the features that I mentioned are available in the TI-84 Plus CE come as part of the built-in OS. With Back-to-School sales (see www.cemetech.net/news.php?id=863 ), the color one is actually cheaper than the monochrome one in many cases.

      The LED that's next to the USB port on the side should light up orange (charging) or green (charged) when you plug it in - if you suspect a problem with the charging cable that came with the calculator, try another mini USB cable. In addition, the earliest TI-84 Plus CE models had a somewhat defective port, where you had to really jam the cable in to seat it properly.
