    Professor McLogan, your videos have been my lifeline throughout this semester! I can honestly attribute my success in the conics portion of my pre-calculus class to you and your fantastic videos. I made the (rather poor) decision to take a 5 credit pre-calculus class through my college's online program where the workload is very heavy, and I have struggled to keep up. Thanks to you, however, I've managed very well these past few weeks. Thank you once again for making such helpful material widely available to those who need it!

    Not sure if this will help, but many of you asked about what to do if the focus has a fraction, as my problem does. What he did without really saying it is he took the 4 from the focus and subtracted the 1 from the vertex to get 3. So, for instance if you have vertex (3,5) and focus (3, 79/16), you would do this: 79/16 minus 5/1 and find the least common denominator to get -1/16 as your "p". Once you do this, just slip it into your formula: (x-3) ^2 = 4 (-1/16) (y-5). Of course, you will need to multiply 4/1 and -1/16 to get -1/4. And then just use all your algebra 2 mathematics to solve the problem. Your final answer will be y = -4(x-3)^2 +5. I hope this is not confusing, if so I can give more details.

  • @marfeliz7143
    @marfeliz7143 6 ปีที่แล้ว +2

    Another way that can help you figure out which standard equation to use is by remembering that the (x-h)^2=4c(y-k) equation is to look for the number in the coordinate that the vertex and focus both have in common. In this case that number is two, which lies on the X portion of the coordinate. Thereby, I remember that I have to use the (x-h)^2=4c(y-k) formula. If the vertex were at (0,3) and focus (0,-1) then I would find that the 0 is the common number that they both share, which is on the x and write the equation for the origin : X^2=4cy.

    Thank you so much for all these videos, I was absent when we first went over this and whenever my teacher does these problems he rushes over it and barely explains. Probably because he normally teaches calculus and IAT is very easy to him and were one of the rare years he's teaching IAT instead of all calculus. I really needed this because most of the kids in my class cheat off each other on tests because no one gets it except the kids who have tutors teaching them and I feel extremely guilty when I cheat on tests.thanks again

      not always above, because the parabola can open down left and right as well. Just remember that the parabola always opens towards the focus and the directrix is the opposite direction perpendicular to the axis of symmetry

      @shhmelloww5382 3 ปีที่แล้ว +1

      The letter p represent the distance between the focus, vertex and directrix. The focus is (2,4) and the vertex is (2,1) we only need to focus on the y, which are 4 and 1. You will need to count the spaces in between the focus and vertex which is 3 spaces. So you just plug in 3 where the p is and get 4(3); 12

    uhmmm what if the p is positive but your parabola opens up?then the 4 in 4p would be negative???

    • @pa3cia126
      @pa3cia126 6 ปีที่แล้ว

      or does your p needs to be negative right away? and do you always multiply it to positive 4??? in 4p???

    • @brianmclogan
      @brianmclogan  6 ปีที่แล้ว

      if the parabola opens up or to the right p is positive, down and left it is negative

    • @pa3cia126
      @pa3cia126 6 ปีที่แล้ว

      Brian McLogan so the 4 in 4p is constant? it will not be negative? the p is the one that will bring negative?

    • @brianmclogan
      @brianmclogan  6 ปีที่แล้ว

      no if the parabola opens left or down 4p is negative

    • @pa3cia126
      @pa3cia126 6 ปีที่แล้ว

      Brian McLogan im sorry i really dont get it? because my teacher once used the equation (x-h)^2= -4p (y-k) so we've been equating it to -4p to get the p. is she correct?

    Amazing explanation.

    What if you have to find the standard form using only the focus?

    • @brianmclogan
      @brianmclogan  7 ปีที่แล้ว

      you will need more information that just the focus

    Hi sir can you help me how to find the vertex, focus, axis of symmetry and the equationof the directrix given the equation

  • @ecartman237
    @ecartman237 8 ปีที่แล้ว

    How would you write the vertex form equation and the standard form equation of a parabola when the vertex and focus are both provided?

    • @ecartman237
      @ecartman237 8 ปีที่แล้ว

      so you find your equation, plug in the knowns, and then fit it into either the standard form or vertex form?

    • @brianmclogan
      @brianmclogan  8 ปีที่แล้ว

      plug it in to vertex form, then expand to write in standard form

    But what if the focus has a fraction

  • @kimberlyneleb6659
    @kimberlyneleb6659 6 ปีที่แล้ว

    is that y=1/12(x²-4x+16) ???

  • @DubJello
    @DubJello 10 ปีที่แล้ว

    What if its vertex (-3,1) focus (-1,1)? Is there a different equation

    • @brianmclogan
      @brianmclogan  10 ปีที่แล้ว

      your final equation will be different but the process outlined in the video will be the same

  • @Sp4cec0de
    @Sp4cec0de 7 ปีที่แล้ว +1

    Howd you find the h and k?(the X minus ___ and y minus ___)

    • @brianmclogan
      @brianmclogan  7 ปีที่แล้ว

      those are the values of the vertex

    • @Sp4cec0de
      @Sp4cec0de 7 ปีที่แล้ว

      Brian McLogan so vertex is center?

    • @brianmclogan
      @brianmclogan  7 ปีที่แล้ว

      no vertex is on a parabola, center is similar for ellipse and hyperbola

    • @Sp4cec0de

  • @carms4975
    @carms4975 6 ปีที่แล้ว

    what if the vertex is (0,0) and the focus is (0,4) ??? how do i write the standard equation
