How to Remember the Unit Circle (NancyPi)

Thankkkk youuuuuu

This is fantastic. Thank you. Once I get the pattern down as you described, it's super easy. I only need to memorize the 1/2, sqrt(2)/2, and sqrt(3)/2 and the rest falls into place.

she looks as the AI

You are just plain awesome, love your way to explain things!!🥰🥰🥰

NancyPi, do you want to be my girlfriend?

Siempre fui amante de la Trigonometría entre ellos el Circulo trigonométrico ....... pero su máxima expresión es cuando se aplica todo las identidades trigonométricas ... me refiero a las ecuaciones y inecuaciones trigonometricas en donde combinas todos estos conocimientos..... ¿Podemos ser amigos?

Best video ever! I am trying learn pre-cal as an adult and this is the best video I have seen so far.

I always start off positive ➕ ,
then everything gets negative ➖
and my life turns
upside down 🙃,
but eventually I make it back
to where I started from🔙,
so in the end everything is just ⭕k..
Then there is 🥧🍰 {2π} 😋 , and Miss Nancy Pi 👩 is serving it to me 😍.

she kinda bad thooooo
lemme get that snap thoooooo

Thanks mam I am from India

Great Teacher, Clever Girl, Decent Woman! This is a scarce combination, nowadays! Congrats Nancy!

So basically 0=2pi ?

Ahhh , why didn’t I know her before 🥹❤️‍🩹

30 years later in less than 5 minutes, I understood ! This, tells me and the world that we have many bad math teachers!
Thank you sweet nancy!

ML thank you NancyPi 🤭🤭

High Theta Hi Nancy from Merlon 6-BAR

There's no way to do it without your participation

I have a test tomorrow on this and this was exactly what I was looking for. Thank you!

Nic and very good

If my math teacher had been this beautiful since the beginning I would have been Ramanujan since now 😍

I understand the math obsession of reducing fractions. But I find it easier to think of the 45degree multiples as 1/4, 2/4, 3/4, 4/4, 5/4 (each multiplied by pi)… Sometimes it’s easier to keep track without reducing.

Excellent , we’ll done

She is cute.

Thanks

Got a crush on you

i luv u nancy pie 🥰🥰

The angels were is 90° what I meant to be....

Thanks for this video.

Literally saved my academic career!! 😭

2nd year as EE major and I still come back here :)

So helpful Nancy thank you !

she not a whamen she my mommy

I think it might be a little easier to write the 1/3rd pies first because then you know that half way between 1/3rd pie and another 1/3rd pie is 1/6th pie

The best thing about Nancy's teaching style is that she knows you have no idea WTF is going on and you hate this class, and she actually acknowledges it instead of pretending everything is okay. Cuz it's not. It's not okay. But we're gonna get through it together somehow.

There is no reason to memorize the unit circle. The easy way to produce the unit circle is to divide a circle into 24 equal 15 degree graduations. Number these points from zero Pi to 2 Pi 0,1,2,3... then take those numbers and multiply them by Pi/12. You will have 8 extra locations on the your unit circle that you can use or throw away. The same method can be used to give you any number of equal graduations that is an even number. Just change the denominator to half that number.

Why use square roots? For example: squ2/2 - why not use 0.7071067811865475 (truncated as needed)?

Thank you Nancy Pie!

4 years using the unit circle and never had it explained this well!

This is the first time ive been able to learn the unit circle in over two years

Great description.

its been 2 days in my precal 2 class and this made so much sense

Why is it that when I put 'cos(pi/6)' into my calculator, I don't get 3^1/2 /2 , but when I put in 'cos(30)', I do? Is it just that my calculator is in the wrong setting for radians? The conversion doesn't work on the answer.

It'll be great to show a few practical uses of all this.

Every time I tell my MOM that the Area of a Circle= πr² (Pie are squared), she reminds me that, NO ... (Pies are round). She's FUNNY.

Personally, I hate RADIANS and love DEGREES. But later on, when you start using polar coordinates and imaginary numbers, you'll see that RADIANS will actually make your unit-circle calculations a lot easier. Just remember that 1 RADIAN = 57.3 degrees and you'll be fine.

Also, remember that (√2)/2=0.707, and (√3)/2=0.866, and of course, 1/2=0.5. (For people who love decimals, its not too hard to learn this)

Thank you

Omg I'm speechless. After all these years of struggling to remember these, I finally get it after watching this video. THANK YOU SO MUCH!!!
