Rapid pace but succinct with no fluff. Had to miss this lecture because of my wife being hospitalized... rewatched and found everything I was looking for, thanks for your time and effort!
5 years later and this is the best method possible. Thank you. Those dislikes are by the teachers that are jealous of your luscious teaching style. thanks for this. saved my ass in discreet math haha
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.
OH MY GOD, I have been struggling so much with binomial factorials but now I finally see the light. I took math courses all the way up to DiffEq and nobody ever explained this as good as you do.
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!
This was very useful, covering some stuff before an exam and realised I didn't know how to simplify factorials with terms such as (n+1), it was clear and straight to the point which really helped
omg i finally understood this after 2 years... thank you for your clear and concise explanation!! rly helps me since i’m taking the a levels this year! :)
really good stuff. no wasted time, straight to the nitty gritty. I'm in calc 2 right now and my algebra isn't great since i skipped college algebra. These kinds of videos really help. Thanks!
Studying for a Calc II exam right now and kept getting ratio test questions wrong b/c I didn't understand how to simplify factorials. I get it now thank you thank you thank you
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
Doing my a levels rn, you're so much better at explaining this than my course book thank you, Mario. 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?
Hi Luis….this video I did here might help explain some things better than I can type it out here: Solving Permutations Equations ruclips.net/video/WAt-oVldRRA/видео.html
I still have a question, why in the lat example you wrote (3n+2)!=(3n+2)(3n+1)(3n) and (3n-1), where did you get (3n-1) from? I thought that we multiply numbers from this (3n+2) to the smallest, just 3n, please explain this moment
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
This really helped... But I have a question, what do I do if this is the given "3 times (11!\7!4!)... Thank you in advence for the help... God bless you always
@@rayyankhan03 for 3 it'd be (n+3)(n+2)= n^2+nx+6 (n^2+nx+6)(n+1)=n^3+n^2+11n+6 I'm sure you don't have to multiply it like this, I think just keeping in at (n+3)(n+2)(n+1) will work

Thank you so much, you are better than my prof who gets paid for making this simple concept harder for us. You are the best!
I reached calculus 2 without knowing how to simplify factorials in expression form lol. Thanks A LOT for this T.T
Helped me understand simplifying factorial after 3 years
Excellent presentation. You have a gift for teaching, making the seemingly complex easy to grasp. Thanks!

Thank you for this breakdown! Your videos helped me get through my Cal II class.
best factorial explanation!
my humor is so broken i laughed when u said "yey three!"
appreciate it, was a little confused, now I'm back on track

Thank you now I know how to do it simply!!
Awesome!
Thanks Mario sir 😊😊

Very useful!
your style for teaching is amazing sir

You are welcome!
Thank youu for the great content! Always a life saver
always didnt pay attention in class or slept and this 1 vid prepares me for test tomorrow loool
Good luck on your test! Glad my video helped you prepare!
Question: Why did you go from 3n to 3n-1 on the numerator. Why did you not stop at 3n?
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

Ok so for the N questions how would I "foil it out" if I want to write a final answer
Questions 3 and 4
@@rayyankhan03 for 3 it'd be

Thanks heaps mate!
Happy to help
0:07 I'm killed me🤣🤣🤣🤣🤣🤣🤣
thank you!!!!
When you do (n+3)! Wouldn't it be (n+3)(n+2)(n+1)(n)? Why do you leave the factorial in the end?
Thank you sir if you're seeing this
thank you
Definitely wished you showed the FOIL steps. I have to find another video now for that part.
xd just expand two brackets and then expand the result by the third
Thank you sir!
