Introduction to Complex Numbers (2 of 2: Why Algebra Requires Complex Numbers)

What an engaging, enthusiast, smart educator. I wish i was in his class in my formative years. Kudo's to him. If only he could be cloned. Maybe someday.

Thanks to the internet, all students have the opportunity to learn from great teachers like this. We need to realize what a beneficial revolution this is and run with with it.

I certainly hope that you mention to your students where these numbers are used in real life, i.e. a whole load of engineering problems that simply don't work without complex numbers. I find a lot of people who learned about the complex plane have no idea why would anyone other than mathematicians care about it.

I like this class, it's very interactive. How beautiful it is to have an interactive math class! The best thing one can ever ask for.
I just wish my student were like this.
We love you Eddie Woo

I like you, I admire you. So I am trying to be like you.

Teaching my little sister Maths with your methods.

I know everything you taught sir but your way of teaching is just awesome . Which brings me back here

[ThatNiceDutchGuy]

Somehow your teaching connects! Thank you for sharing these gems.

[timello]

Congratulations! You are a really good teacher.

Simply superb. I can't remember in my entire study tenure to have find maths teacher like you. The way you explain things in a simple way is superb. Wish I could have studied under you.

In electronics, the x+iy becomes x+jy, because i is the sign for current, i learned complex numbers as P=A+jB, and never understood how the come up with something like the square root of -1, but it works in filters and stuff in electronics, electronics is leaning on complex numbers, i just applied the rules i've learned in the past and it is awesome to see it just works!

Brilliant! I like the the way you introduce complex numbers. I am not so sure if it is appropriate for this class, but a little bit of more history behind as a story might be extra icing on the cake.

Writing zs like 2s haunted me for years, first with complex numbers then with impedandec(also complex numbers).

It's important to note that R also has transcendental numbers which are not algebraic numbers.

7:41 I much prefer a+bi for 2 reasons
1. i is after the coefficient which is more standard
2. It has similar notation to trig (which is very important for complex numbers)

I get so stuck on watching the videos one after the other and I forget to like the videos.

i have a calc exam in two days and getting info from real techer's in real class rooms is so much better than online tutorials bc its not so much revising as it is remebering how it works

Well, as R. G. Collingwod said, if you have got one gram of pupils admiration, it is worth more than a ton of admiration from others. You have got a ton of pupils admiration.

If you do not understand imaginary number, read Andresen's "The Emperor's New Clothes". It helps to comprehend this along with relativity.

[DDranks]

Uh, reals like pi and e don't belong to algebraic numbers. They are transcendental numbers. (He's still right about that they form an algebraically closed field.)

[Nick-uidr]

No I dont have that specific use of it in my mind.... just was curious once about maths so just tryiing it again for fun or time pass. :)
