7:03 For the (4-3i)(4+3i) you can use the formula a^2-b^2 = (a + b)(a - b) so it would be 16-9i^2 just like your answer. This is just a faster way to do it. Hope this helps!
I have just encountered complex numbers for the first time while calculating the magnitude of frequency transfer in an RC filter in a college class. Had no idea what a complex number even is, but now I understand what is going on. Thanks a lot!
@@moznalutaibi3080 People can do work programs to get high school credits while working at a job instead of taking the actual class. My grandmother actually did this and the only math she took in high school was Algebra 1 and Geometry. She also took less classes in general because of the work program. And also, people don't need to do precalculus. Most people choose statistics instead of algebra 2 and precalculus.
Thank you so much!! I was really nervous for school because I didn’t learn this unit but this really helped me catch up. Imma rewatch it like 50 times….
You're the goat, you're saving so much time by cutting the fluff I experience in class and teaching in a straight forward way. Now I'm skipping more class and just watching you to learn how to do my homework and for review for tests. Saving a lot of time and stress.
idk about lord but you are my savior. thank you so much Im in alg2 honors and i was doing REALLY bad (CD range) but then you made it all understandable and now I've a B- which will hopefully go up to an A like before. THANK U
@@sanopann1896 nope GED isn't hard. There's a high chance you will pass the GED's math section if you have completed 8th grade maths section on Khan Academy.
Greetings from Nigeria 🇳🇬 🙏 Thank you so much sir Your mode of teaching is the best I’ve known yet 🙏 This would really help me in my semester exams 🙇♀️ ❤
can someone pls help me?? i have a problem on a test and it just says solve 7+3i i’m in ninth grade and i missed a few days so i don’t understand it. could anyone tell me how to solve it and what it means. it just shows a graph.
I have a doubt, at 2:42 if I write, i^33 as (i^3)^11 it becomes (-1)^11 which is (-1) , is something wrong with my calculation or do we have to try to bring a positive outcome if possible?
because square root of -1 equals 'error' on a calculator as it is (I)imaginary so it's the only case you use i really ig, I was also confused by it for a few secs
PLEASE ANYONE ANSWER MY QUESTION, if I want to write the square root of something that is negative but it also doesn't have a non decimal number as it's square root what do I do!???

(-3i+4)(3i+4)=
(-3i*3i)+(-3i*4)+(4*3i)+(4*4)=
9+(-12i)+12i+16=25=5^2
Nice! Useful information for the basics
I subscribed your channel
Man you are good at this
Greeting
Thanks sir, you just summarised my whole text book chapters on Complex numbers 💯

did you not go to highschool? genuine question
@@moznalutaibi3080 My highschool couldn't manage to teach us this because of COVID. We were really behind in math.

you teach me all the things my math teacher fails to explain. thank you.
This is exactly what I was looking for. Thank you!!
I CANNOT STRESS HOW MUCH THIS HELPED ME. THANK YOU SO MUCH! I OWE PASSING MY MATHS EXAM TO YOU.
I appreciate that all of theses tutorial videos on youtube show people how the forumla works, but nobody tries to explain what an imaginary number is.
Thanks alot. Greetings from Tanzania
Plz watch this video and give some advice plz
High school student here. I find it really interesting and time killing. Imaginary numbers blow my mind

is all the test of GED is hard big bro is it all about reasoning

i feel like im learning basic maths all over again
I am still confused
Real.
please help

Greetings from China!
That was great man! 📚🙏
How have I not followed you since ... Thanks very much for a well explained video on complex numbers . You broke it down well ❤
i immediately understood this when i noticed that if we put square root of i to the second power it becomes -i
Dude, now I'm studying engineering. Guess I'll be stuck with your vids forever 👍
I like the name. Wowaka?
My algebra 1 teacher won't teach us this until algebra 2. I'm glad I could learn this on my own :)
thanks for making this video in math class i had trouble but now i am good
Your explanation is really good
We want people like this
Also can please do videos about quantitative analysis course ?? Like decision making .. forecasting methods and etc ....
Assalamualaikum
God bless you
Oh thank GOD you exist
He is God
Thank you sir!!!! When will the next part be uploaded?
You are the man 🙆
Thank you for Sudan 🇸🇩 I like all your vid dude
Thanks!
i always go to u when i need help in math
Thankk you, it is very beneficial.
i ^ 4 = 1
i ^40 = i ^ 4 ^ 10 = 1 ^ 10 = 1
i ^ 43 = i ^ 40 * i ^ 3 = 1 * i ^ 3 = -i
Thank you sir
May you please solve for this question 14/i (complex number)
terimakasih bang, sangat membantu memahami FISMAT IB
It's so cool✌️👍

girl im-
no please
What are imaginary numbers used for?
really great !
this guy is the goat
7:58 do we just have the copy the denominator (25) and insert it to standard form (a + bi) to make it into standard form?
can someone pls help me?? i have a problem on a test and it just says solve 7+3i i’m in ninth grade and i missed a few days so i don’t understand it. could anyone tell me how to solve it and what it means. it just shows a graph.

Hey ya 1st..
Thanks for the basics...
Can you plz make videos on advance problems related to this topic
teaching it better then my evil algebra 2 teacher
i wuv u very much
U will go to heaven ❤❤
Not bro just casually explaining imaginary numbers in 14 min while it took my teachers 5~7 hours
11:10 Shouldn't x be equal to plus or minus 6j? Since not denoted, we can say that -6 is also solution
😂😂😂😂 Ur funny
@@PR0DBYKANI how so
Find the error: e^(i*π) = -1 => raise both sides to 2 => e^(2*i*π) = (-1)^2 = 1 = e^0 => 2*i*π=0 => i=0
When reducing i^x power can’t you just mod 4 and count?
5:14 how did he get -i and -6?
-2i x 3i = -6i²
i² = -1 so it is (-6)(-1) which = +6
then the middle terms were 15i and -16i so he combined them and got -i
@@gutdupois2809 thank you🙏
you sound like that one really relaxing voice from TedEd
I love you ♥️
I’m confused, I thought that i is the square root of -1, if so why did he just write i in his example of i^33 instead of the square root of -1?
because square root of -1 equals 'error' on a calculator as it is (I)imaginary so it's the only case you use i really ig, I was also confused by it for a few secs
i am not failing my final exams. thanks

U teach at mmy whole school from Year1 to 5

in 11:18 how come that there is two solution 6i any body help me
PLEASE ANYONE ANSWER MY QUESTION, if I want to write the square root of something that is negative but it also doesn't have a non decimal number as it's square root what do I do!???
There's no answer in real world terms. To answer that question you need to use marvel characters...
why is -2i * 3i = -6i^2 and not -6i
wait, I think it's because -2i * 3i = (-2 * 3) (i * i) = -6i^2, am I getting this right?
@@JRSNT.02 yes
3:13
the hyundai i20 should be "hyundai 1" and i30 should be "-1"
why are you saying i but you keep writing c? just call it c
Hello, why is i^7's final answer -i? Isnt it the same as i^3?
i^7=i^4 multiplied by i^3, which yes is the same as i^3 times 1, or i^3. i^3 is -i, since it is -1 times i.

. I have no idea what any of this means
why is bro writing the i like a bracket
loveeeeeeeeeeee
No idea
I am no closer to understanding any kind of complex mathematics
It's not complex, it's imaginary. You need to watch all marvel movies first...
dawg what
i didnt even know an i was in math
I don't understand😭
goat
wallahi im finished
x^(2) + 36 = 0
x^(2) = -36
x = sqrt (-36)
x = error
x=6i
I feel ripped off. I was waiting for the Pi to the I. Lol
Do you mean e^pi(i)? Thats -1.
