Because of the assumption “3k>=2k+5”. When she substitutes n for k+1, the right hand side becomes 3^k+1. When the right hand side got multiplied by 3 through substitution, she also multiplied the left hand side by 3 to make the maintain the balance (3^k >=2k+5)
Colin Fontaine No, it’s all written the right way for me and then the video is flipped after filming. So I’m right handed but it looks like I’m left handed
I think shes just writing on a piece of acrylic with a sharpie. Dont think its a program. Unless you mean the editing software in which I have no idea. :P

Helping us all understand discrete math while writing backwards with your left hand, brilliant.
she writes forwards and then flips the camera vertically when editing the video
@@dn6824 woooosh :(
I watched like 3 other videos on this, but yours was the most clear and helpful!!! thank you!!
@Robert Bennett Instablaster :)
Struggling to understand these for 30 minutes just to find this one and clear my confusion in 4.
Are you writing backward this whole video????
@ClintonConnelly She wrote properly and then flipped it in editing so its not backwards for the viewers
BEST video on this topic i have ever seen, never write comments but this deserves one
Thanks Whitehead, you are helping me for my semesters.
Math is the only subject I fell good at ,but my teacher are teaching so easy problems .this video really taught me skills I didn’t know.thanks!
omg guys it's Orlaith Dirac, the inventor of Dirac Delta!
@@eldi wait wait wait, are you the REAL Jonas? The inventor of the Wheeler-Jonas equation? I am actually gonna cry rn
yeah just cleared the thick fog. thank u
Math made simply and comprehensible!!!
I failed a midterm because I didn't understand mathematical induction...but I'm not going to fail the final, thanks to this video.
Loved the video. Really helpful. Keep up the good work👍👍
Nice explanation
Great explanation thank you so much and please continue
Thank you so much
everything just clicked... thank you!
very educative
Lit 🔥🔥🔥
Explanation
👍

Is she actually writing in mirror? Always wondered this, or does the program she uses flip it?
She writes normally and flips the video while editing
Thank you so much❤ mam
Great explanation
terrific!!
keep it up!!🙏🙏
Watching this 20 minutes before my test
best explanation
Thank you. :-)
Very clear.Thank you.
you re the best
Very helpful thanks
Thank you!
thank you, you just earned another subscriber
Nice one
Thank You so much!
for sk you use k+1 but your univrse is set of positive integer that greater than 1 so, sk have to k+2
Great video!
thank you . keep it up !!
Beautiful
Thank youuu 💙
Why did you multiplied 3 to 2k + 5?
Nice
YOU LEGEND
Omg I'm actually thankful
Book my class uses.... does not hold a comparison to this, thank you!
thank you
i failed math hl
Thank you
THANK U
😭😭😭😭thank you 😭😭😭😭
How I wish I could use this method 😭
1:44 why do we multiply 3 * 2k + 5
Because of the assumption “3k>=2k+5”. When she substitutes n for k+1, the right hand side becomes 3^k+1. When the right hand side got multiplied by 3 through substitution, she also multiplied the left hand side by 3 to make the maintain the balance (3^k >=2k+5)

What technology is this?
Thnk u ❤️
thanks :)
do you actually write backwards

@@HeatherDavis THIS is big brain time :o
@@HeatherDavis whoa
gorgeous
Can you please give me the solution of n^3
Very helpful
And I should hire u as my personal teacher😜
Are you writing backwards?
Please what is the program used in the explanation?
I think shes just writing on a piece of acrylic with a sharpie. Dont think its a program. Unless you mean the editing software in which I have no idea. :P
reverse writing
can't understand a thing voice is lagging behind the video
how is 9 greater than 9 lol
Exacty I don't get how 9 > 9
For n = 3 the inequality is true but for n = 2 it is untrue
So why is 9 > 9 ???
It's greater than or equal to

Find for me n+1÷2-n-3÷4< n+2÷3
you look priety if you wear hijab it will suit on you
thank you, would like to suggest you speak a bit slower, so that it is easier to follow your thought process.
Good explanation
Great explanation
