im in a sophomore year engineering class and none of the stuff made sense, and i had never seen a cosine or anything like that and now it makes all the sense in the world to me thank you so much you kept me from failing last semester
Great video helped alot, just interest where this is filmed? normal classroom? uni lecture? Most schools I know of are pretty hard on filming in lessons, nice to see wherever you work they realise the value of having recorded teachings.
This is so hard to understand as a grade 9 student who have been in online classes since 7th grade thanks so much u teaching makes me understand faster
I think that "i", "r" or "k" are the most suitable variables used to show which number the summation starts with (the variable is referred to as the index). "n" is usually used to indicate the last number of the summation. However, they are just variables so they can be used interchangeably in different textbooks or even online.
You can technically use anything as long as the letter is not already reserved for something in the problem you are solving, if your problem has imaginary numbers in it, then yes don't use i, use something else. There are some variables which are normally associated with this kind of problem, in my uni we usually use i/j/n
doesn't i mean index number? we use n meaning nth term. i hate how they use other terms in different books and when i try to learn from a different source sometimes the formula gets all jumbled up so i have to rewrite all the sht just to match the formula given to us.
yes, actually. it just looks different but it's the same thing. the exponents in the denominator of your answer can be added because the bases are the same.
Your channel has helped me immensely. If you read this, please know that you at the very least helped a confused student.
Hi Distefano! happy to be able to help you out with your math
"it takes practice" thanks for that☺️ im really struggling rn about this lesson and hearing that from you makes me feel like im not the only one
of course you are not!
Love these videos! They are very helpful for my College Pre-Calculus classes! Also my finals! Keep them going please!
will do, keep up the hard work!
He's always so annoyed with his students haha

I love your videos. I am a mom helping her daughter with algebra and calculus
I like the live classroom lesson. Keep it up! Just discovered your channel, looks good. Couldn´t help myself to notice how you write your "6".
haha yes I am enjoy making the live lessons, it is weird isn't it
This is so hard to understand as a grade 9 student who have been in online classes since 7th grade thanks so much u teaching makes me understand faster
so what it means is u gotta have to practice and use trial and errors to find the rules and be a sigma 🗿
Thank you so much.
Just like Cady Heron said, Math is beautiful because its the same everywhere you go
If i use n+1/8 would be okay or not!!
What grade level do you teach sir?
how do i find formula of sum of series whose general term is (1/n^2 +5n +6)
3 times 2 is 9?
I had the biggest brainfart of my LIFE! Thank you for demonstrating this!! It's so simple UGH.
You are very welcome!!
Do you have to use i? Or can I use what ever? i makes me think of the imaginary numbers.
Cringy 7-Year-Old You can use ‘i’ or ‘r’.
No you can use “n”, stands for “nth term”. “i” does mean imaginary number.

Why is it 2 to the i + 1 as the denominator and not just 2 to the i?
because i starts at 1 so if it was just 2^i it the first term would be 2^1 or 2 in the denominator
What is i?
@@kaboomaroom1629 the variable
isn't it 2^i(2)?
adults: nice video!
Millenials and gen Z/alpha: sigma 🍷🗿
Thank you sir
1:53 *3*2=9* 🤔🤔🤔
yea,,,,,,, that is not right
Lol, but the video was helpful, thanks for making it!
Randy Orton doing math videos? cool
I feel 10x smarter everytime I solve these types of problems.
?=129/64=2(1/64)
The rule given to the denominator doesnt makes sense to me, care to elaborate?
bro its SIGMA 🍷🗿
Figured it out.
same, cause doesn't 2^1 + 1 = 3? it doesn't make sense
Coldn't it also be (2^i)-1/2*(2^i)
That is literally the same thing.
yes, actually. it just looks different but it's the same thing. the exponents in the denominator of your answer can be added because the bases are the same.
I wish you are my teacher
AWESOME
: )
One fifth of the sum of 9 and 12
(2(n-1) + 1) / 4n
okay
Shoutout kay sir ben.
Maraming Salamat!
Salamat din 🤘
Baldy Slap
he made a slight mistake he said 3*2 right it's ouveusly 6 right but he said 9
🤦🏻♂️
3x2 is 9😂
i am g7 and i want to learn this
