    *Watch out, If you have a go yourself, the last question should read as x² - 2x - 4 not + 4, so be careful.*

  • @jamesoliver8577
    @jamesoliver8577 8 років тому +1

    Excuse me , aren't the solutions of the last equation :
    x1= 1 +√(3)i and
    x2= 1-√(3)i ? . Thanks a lot

    • @TheCalculatorGuide
      @TheCalculatorGuide  8 років тому

      Well spotted thanks. It is the question that I put in wrong though. Should read x^2 -2x -4 rather than plus 4.
      Will look at amending as soon as I can or doing a replacement video.

      +James Oliver Thanks again James. Have added an annotation to the correct equation. Will look at redoing the video at some time as it is a little long as well.

    is there a another way to solve complete the square on since I had casio fx300es Plus model do not verif?

    • @TheCalculatorGuide
      @TheCalculatorGuide  4 роки тому

      Not with the fx-300ES no. The method shown in the video has been somewhat superseded by the polynomial silver feature on calculators such as the fx991EX and graphics. Best advice is to update your calculator when ready.

      I don't think there is any facility to lock a scientific calculator to prevent others from using it. It isn't that advanced I'm afraid.

    • @TheCalculatorGuide
      @TheCalculatorGuide  7 років тому

      +Saif Sleepy The model shown does not have a Equation solver. What if your exam asks you to show an equation in the form (x+a)^2 + b? What if it asked you to show your working? There are many ways a question involving completing the square could be presented. I agree that an equation solver would be the fastest way to obtain a solution, but that's not what this video is about.
      I hope you exam goes well, but take care with what the questions are asking you to do. All the best.

      thanks, what about finding the exact value of Sin (15*) ? ; teacher did sin(45*)-Cos(30*)....;
      but every time i plug it in the calculator to find the exact value it get a decimal point.. any ideas?

    I could have completed the square far quicker by hand. /Regards

    • @TheCalculatorGuide
      @TheCalculatorGuide  5 років тому

      I am sure you could.

    • @GeoCalifornian
      @GeoCalifornian 5 років тому

      The best use for a calculator when completing the square is when solving by hand, --you often end up with an improper fraction (after taking one-half the middle term, and then squaring)... like say, 6/4 or 5/2, on the left-side of the equation, that you must then move over to the right-hand side of the equation to finish your work.
      Use the scientific calculator to help you decide whether to use the improper fraction or convert it, to use its decimal form, to complete your answer. /Regards

      You can get it from www.sciencestudio.co.uk/casio-fx-es-plus-manager.html?category_id=34 although it is a bit older now.

      That is a subscription that is available from the Casio Education website. You get 90 days free trial. It is currently around twelve pounds a year. You can buy the code from science studio or online.
