Trigonometry on the Unit Circle (1 of 3: Introduction) 

As long as you enjoy teaching, dont stop posting videos please. They’re much appreciated

Chatty kids: "Have to be here." Me, older than my professor and struggling with Calc: "STFU, little rats. Let him speak."

Taking AP calculus AB right now and I'm realizing most people don't have an intuitive understanding of trig functions and the unit circle. Best RU-vid math channel I've ever seen

Hello Mr. Woo! I'm from India and for sure that your videos are nice and easy to understand. You helped the children all across the globe and for this, we all are thankful to you.

Wow, I think I get it! I'm not really clever enough naturally to understand all this hard stuff, but I stuck with the video and after my brain was subject to great heat and pressures it metamorphosed into a different, cleverer kind of rock because I got it!. It felt like I'd gone up a Buddhist mountain somewhere and come down a different, transformed person. Seriously, thank you so much for the great explanation of the triangle in the circle, this is the 1st time I understood that stuff about it.

THANK YOU! My teacher hardly explains this stuff to us!

Thank you so much, you're an excellent teacher!

This guy is a wizard. He should be teaching maths to the world via videolink!

This guy really explains beautifully.

Thank mr Eddie for all your videos! They’ve been a big help!!!

I LOVE YOU !!!!!! i kept saying "OHHHH" throughout the video, i have been struggling with this so THANK YOU SO MUCH !!

He knows he nailed that circle

Thankyou sir for most knowledge. many lucky pupils to gain your intellect. god bless

I only learned this stuff this year oh damn

Thank you so much

my hint is SohCahToa sin = opposite / hypotenuse cos = adjacent / hypotenuse tan = opposite / adjacent thats why i still remember it 12yrs after i graduate 😉

The board was difficult to see at times due to the brightness of the picture. Other than that, excellent as always.

I was having some problem finding online teacher..... He is a perfect teacher for mathematics🙃. But can anyone recommend me a chemistry and physics teacher?

Wow ! They teach this in year 10? I heard about the unit circle for the first time in year 11🤔

So much help, thank you!!

Draws a perfect circle. What!? What?

What was the question at 10:10

*Draws a perfect circle* "what?" Woo is such a chad

"If you dont learn this in grade 10 you'll never understand it" - me in second year uni using good ole eddie to get me through my maths class bc i never learnt this concept

Well now i know how/why sin can be presented as ratio of sides or sin can BE a side. I really didn't know that.

Eddie WOO HOO

I really wish he was my teacher...

oh my god,

WHITE BALANCE

2:33 wow he drew a nice goddamn circle
