    Sir, you are life saver. I learn more from 10-15 min video then whole week sitting in class. Thank you very much for all you effort. Keep up the good work.

    math is hard for just about everyone (me too) - not all things in life are simple.
    keep studying and you will be surprised at how easy it all becomes!! : )

    You are awesome man! I'm currently about to take my ASVAB test to join the Airforce and since I graduated in 2007, I can't remember everything I learned in HS. This video and many more that you have make it super easy for me and I'm sure I will do awesome on the test. Thank you for the videos and the work you put into them!

  • @psykovskee
    @psykovskee 10 лет назад +5

    The explanation of 0 factorial is missing here, yet it's very important to understand, because the idea of factorial comes from the set theory, where you need to find all possible way to order all elements in a set.
    0! Represents a set with 0 element, it has only 1 possible outcome of ordering it, which is the set itself

      @PaulSmith-gi5bf 7 лет назад

      ik the feeling, teachers are way too fast-paced so they can pump out every chapter they're forced to teach until the end of the year. It completely ruins education

    Thanks for the refresher! Or this video is actually pretty sweet! I can learn something out of these videos! Free learning! I love that!
    If you wanna stress your brain with math, you got to do factorials. I tried 8! In my head but i kept forgetting numbers that I need to work with so I have to go all the way back to start from the beginning of the sum. I hate it when that happens! Haha.

    Would you say that just constantly doing lots of questions would imrpove your skill in that area, or is it better to focus on the formulas and logistics behind it?

  • @maylisa6073
    @maylisa6073 10 лет назад +5

    OOoooohh I get it so, 35! 10!/ 23! 6! = (35*34*33*32*31*30*29*28*27*26*25*24) (10*9*8*7) because I simplified the 35! with the 23! first and then the 10! with the 6! second. Although that would still take a long time to solve. If you didn't completely solve it it would change to (35!-23!) (10!-6!). So ya, your video was helpful.

    in your video about binomial probability, how did you factor and cancel using the 2nd denominator factoral? uncertain on how you did that.

    What about limits? for example as the limit approaches infinity and n!/2n!+1 type problems? How would I know if it diverges or converges. I know for this problem it would converge to 1/2 due to using the HA test but what if they were not the same, how would I work that out?

    What if you have n! in numerator and (n+1)! in denominator.
    n!/(n+1)!
    I am trying to learn how factorials simplify in evaluating sequences and series.
    What throws me off is the denominator with the factorial outside of the parenthesis.
