    The one dislike was a teacher who’s jealous of this amazing teaching style.

    Wow Just WOW! I'm in calculus 2 right now and this video really helped me with ratio tests. I really don't remember learning factorials before this class. They're cool and fun to do. But thanks so much for this quick video to summarize the simplification process!

    Regarding your website; it's fantastic that you've taken the time to put all the videos in order. There are barely any teachers online who bother with organizing their videos which makes following them unnecessarily hard. I hope your channel gets more recognition. You truly deserve it.

    Factorials always confused me, especially with how I just got thrown in the deep end with finding the limits of series using the ratio test. Thank you for making a video that explains factorials so quickly, without wasting any time; the 0! and 1! parts were extremely helpful as well!

  • @kurtgardner7152

    • @MariosMathTutoring
      @MariosMathTutoring  5 ปีที่แล้ว +2

      Good questions Francisco....you want to keep going until the factors in the numerator and denominator start to match up so you can then cancel the ones in common and see what remains...hope that helps

The only question that I have is what do you do when the denominator is seemingly larger than the numerator, rn I'm stuck on a problem where I have to prove that nC2 = n(n-1)/2 how would I go about that?

  • @91dgross
    @91dgross 2 ปีที่แล้ว

    can u explain how in problem 3 you are able to multiply by (n)! in the numerator? my understanding is that after you multiply (n+3)! = (n+3)(n+2)(n+1), -->(n+1) is the last factorial, or the act of multiplying by 1. my question is, if the goal is stop multiplying when we get to 1, how can we just spontaneously throw up (n)! to multiply by when ..*(n)! does not represent 1 in this case, as (n+1) does
