    Professor RobBob, thank for demonstrating the use of the Ti-NSPIRE calculator for graphing parabolas/quadratics. This calculator is fantastic when it comes to graphing, solving and analyzing equations.

    It took a long time to warm up to the NSPIRE. But now that I have, especially with teaching statistics, I really appreciate the new calculator...a lot. Color helps a lot, because the black & white NSPIRE is hard to read. Force yourself to remove the 84 keypad and I think eventually you will feel the same.

  • @profrobbob

    There is a way to chance the settings for the table, but to find a y coordinate for one x value, I would just go the a calculator page and type in the function with that particular value of x substituted in.

  • @profrobbob
    @profrobbob  11 років тому

    Since you have a closed interval for your domain. Plug -5 and 5 into your function to find the left and right end points. You then go the the analyze graph menu and identify the minimum and maximum values within your closed intervals. The smallest and largest y values you get from all of this will define your range.

  • @profrobbob
    @profrobbob  12 років тому

    With the software update these calculators are a bit different now. I need to do some new videos. I am glad you figured it out:)

  • @profrobbob
    @profrobbob  12 років тому

    Do you not have drop down menu in the upper left corner to change the view when looking at your virtual calculator? I have the teacher software but I got it at a training...I don't know how much it costs. You can look at the TI website.

  • @profrobbob
    @profrobbob  12 років тому

    If you are doing great with the ti-83+ and you don't feel like you need another calculator...just keep using it. If you like gadgets, and if you are going to be taking statistics soon...especially:), and you have the money, I love my new NSPIRE CX. Be careful getting the CAS version though because you may not be allowed to use it on your tests. Check with your teacher and any standardized tests you may have to take in the future. The color versions are MUCH easier to read than the non-color.

  • @profrobbob
    @profrobbob  11 років тому

    f(-5)=-24, f(5)=126, relative max (-3.08,6.04) and relative min (1.08,-30) so the range is -30 to 126

  • @profrobbob
    @profrobbob  11 років тому

    Without seeing your calculator and playing with it myself:) try going to settings from the home screen go to handheld setup and select Restore. If your are just using scratch pad, you can go to scratchpad menu and select Clear Scratch Pad

  • @profrobbob
    @profrobbob  11 років тому

    Go to settings and status of your document, chose document settings, and change angle from Radians to Degrees. You will need to make your x axis much larger. I don't know what math class your are in, but if you are starting to study radians you should stick with radians.

  • @profrobbob
    @profrobbob  11 років тому

    Your question made me realize I forgot how to change the color. It is not a right click but with the graph selected you can click CTRL then MENU to open a window where one of the choices is color :D

  • @profrobbob
    @profrobbob  11 років тому

    You can take the equation and solve it for y so you can put it into the calculator, but you will need two equations. One equation for the positive square root and one for the negative square root.

  • @profrobbob
    @profrobbob  11 років тому

    The newer software allows you to put in equations of conic sections and within the menu is an option for horizontal parabolas...though I have not played with that menu.

    I have a TI-89 Titanium and I actually had some first-hand experience with the TI Nspire CX. Man, that thing was a beast! It certainly took me some time to get used to the controls but overall it was pretty good. It's certainly overkill for high school Algebra I, Geometry, or Algebra II but I'm heading into the engineering field and I'm greatly considering getting the CX CAS. (Also, it seems like the CX CAS can do implicit differentiation which certainly will help with my AP Calculus AB class!)

    Hello professor, I have a problem with my TI-nspire CX. I bought it about a month ago and it was working fine, then I was messing around with it and now I can't seem to graph things with it. I now get a syntax error or a you don't have access to this message. I installed the student software and it has not changed anything. How can I fix this problem? I am doing final exams, they are due tomorrow, however it is pretty hard without my calculator. I already don't understand this stuff as it is.

    • @profrobbob
      @profrobbob  9 років тому

      Supergoose sevens I don't know if there is a option for that in the menu. The y intercept is usually much easier to find than an x intercept. Plug 0 for x into your equation and usually just a little bit of arithmetic will give you the y-intercept. Using the calculator, I think you may have to view the table and go to where x=0.

    I guess being from an older generation, this calculator just has too much of a learning curve. I purchased a first generation Inspire with the interchangeable Inspire/84 keypad and I use the 84 keypad 99% of the time. Even after buying a newer touch keypad and downloading the newest operating system, it is still a very frustrating machine. I think TI would have done much better to give the TI- 84 a color screen with higher resolution than invest all their money, time and energy in the Inspire.
