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)
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
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

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 :(
Not the brightest are u
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.
BEST video on this topic i have ever seen, never write comments but this deserves one
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
Why did you multiplied 3 to 2k + 5?
Thanks Whitehead, you are helping me for my semesters.
Thank you for doing this great explnat
yeah just cleared the thick fog. thank u
Loved the video. Really helpful. Keep up the good work👍👍
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
I failed a midterm because I didn't understand mathematical induction...but I'm not going to fail the final, thanks to this video.
Are you writing backward this whole video????
@ClintonConnelly She wrote properly and then flipped it in editing so its not backwards for the viewers
Some left-handed ppl have this ability and even for Chinese characters they are able to do that naturally
Unless if she’s writing in a mirror, of course
Great explanation thank you so much and please continue
are you wearing iluminaty cross ?
1:44 why do we multiply 3 * 2k + 5

thank you, you just earned another subscriber
for sk you use k+1 but your univrse is set of positive integer that greater than 1 so, sk have to k+2
Lit 🔥🔥🔥

you are special one thanks
everything just clicked... thank you!
Math made simply and comprehensible!!!
You’re amazing
What technology is this?
terrific!!
keep it up!!🙏🙏
Thank you so much❤ mam
you re the best
Omg I'm actually thankful
Watching this 20 minutes before my test
Thank you so much
Great video!
very educative
Very clear.Thank you.
best explanation
Thank you!
thank you . keep it up !!
Good explanation
Thank you. :-)
Nice one
Very helpful thanks
Thank You so much!
Please what is the program used in the explanation?

Thanks
Thank youuu 💙
Book my class uses.... does not hold a comparison to this, thank you!
YOU LEGEND
thanks
How I wish I could use this method 😭
Great explanation
Can you please give me the solution of n^3
Nice
do you actually write backwards

@@HeatherDavis THIS is big brain time :o
@@HeatherDavis whoa
thank you
i failed math hl
goat
Thank you
THANK U
😭😭😭😭thank you 😭😭😭😭
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

And I should hire u as my personal teacher😜
Thnk u ❤️
I need only
thanks :)
gorgeous
thank you, would like to suggest you speak a bit slower, so that it is easier to follow your thought process.
reverse writing
Find for me n+1÷2-n-3÷4< n+2÷3
you look priety if you wear hijab it will suit on you
