    I know this is one of your older videos, but the first fraction would be 21x^2/400 instead of the approximation of x/19, and that's probably why you didn't remember getting that :) This was really helpful; thank you!

      +Marguerite R I have having math block, would you mind showing me where I went wrong so I can create an annotation to not confuse other students?

      +Mr. McLogan's Math Channel +Mr. McLogan's Math Channel in the end of the video where you approximated 400 divided by 21, you can leave the fraction to be 21x^2/400 + y^2/25 =1 so it is more accurate.

      haha of course! absolutely, should never had approximated, left as a fraction, very well, thank you for keeping tabs on me!

    Hi sir! I just want to ask how did you get 21/25?

    • @seabongteencaratdeul909
      @seabongteencaratdeul909 4 роки тому

      1- 4/25
      = 21/25

      Same questionnn

      In order to solve whole number with fractions easier, you need to convert the whole number into a whole fraction, for example here:
      1, you will convert it into fraction with the same denominator of 4/25. So the will be 25/25, then solve.
      25/25 - 4/25 is 21/25.
      Hope it helps!!!

      1 becomes 25/25
      25/25 - 4/25

      Brian McLogan what if they give me vertices (2,3) and (-8,3) passing by (-2,1) to write it in standard from for an ellipse??

    • @brianmclogan
      @brianmclogan  7 років тому

      The distance between your vertices is 2a, divide by 2 to find a. The center is the midpoint of your two vertices. Now you have a, h and k. (-2,1) represents x and y. Plug them into the equation and solve for b

    I couldn't understand why did you replace a with 5 in the 2nd line
