- 👉 Learn how to find the reference angle of a given angle. The reference angle is the acute angle formed by the terminal side of an angle and the x-axis. To find the reference angle, we determine the quadrant on which the given angle lies and use the reference angle formula for the quadrant to find the required reference angle.

This guy is more useful than my math teacher. Well done good sir
You’re a life saver right now with quarantine, thank you 🙏🏽
I just can't seem to understand this for my life man.
graphing angles in standard form?
Brian McLogan Actually I finally figured it out. I kept watching your video over and over until it sunk in. Thank you thank you thank you my good sir.
you are very welcome! I have a lot of videos on the topic but glad it finally sunk in
Hello sir iam from india
Thanks again Brian, your videos have really helped. You have a knack for making the process make sense, not just following the steps.
bruh, i got it. I just kept on looking back and forth with the unit circle and video. Thank you Sir!
2021 and I still cant understand this
This saved me so much time of understanding what the denominator and numerator mean when it comes to what they do in the unit circle. The fact that it was a fraction confused me but knowing the numerator is going to be a number with pi, therefore states how many (half circle) times it'll it wil spin in a sense. Denominator is still a little tricky though
You are a hero
You made this is so simple! Thank you!
Very helpful. Your better then my Russian profesor. Thank you
Thanks
Who created the reference angle?
haha sir reference angle himself, just a helpful way to evaluate angles they are not a must though
Perhaps someone running in circles to get to -10π/3 but wanted to walk less? LOL
(I know Im 4years late to the joke but I'm taking Trig now. My teachers good, I just like it explained as many different ways as possible)
How in the world is he counting these lines on the graph? Looks like he's skipping some and not others. I'm so lost.
I do not get it. :(
Thank u so much since I left China my math ability decreased!
ahhh, happy to be able to help you out!
this man is the GOAT
I’m so confused on the graphing portion :/ all of it confuses me, such as how many quadrants are you supposed to have and how do you know, and how do you know what each side is equal to…
What if I have a problem like 28π/9... for the refernece angle do I need a denominator thats on the unit circle like 3, 4, or 6?
I think I cried when I say I got the problem I was working on was correct thanks to this video, although I had to guess since it was -6π/5
are all reference angles just pi over the original denominator?
I actually never realized that but the answer to your question is yes
Was this in English? Can you make another video in English please?
Maybe it's the weight I lost?
Im sorry but your weight loss, actually made things more confusing
I need help badly. I'm in Algebra 3-4 and stuck on a question. The question is what is a reference angle but when I put your definition it didn't help
Can you also keep adding two pi instead of 6 pi over 3?
yes but I added 6pi/3 since it has common denominator
I know this already
But why am I watching this??
why the 6pi/3?
Can't you just put 10pi/3 into a mixed fraction so 3 and 2pi/3 and so the ref angle is just pi/3?
HHEE HEEEEE, all i needed was that CHEAT SHEET MUAHAHAHA
why
im dying
So what happens if the reference angle is lets say: 3.7 do we just take 3.7 - 3.14 ?
if the angle is 3.7 then yes the reference angle will be 3.7-pi
Wow thank you so much. I spend more time watching your videos than watching my own professor. I'll be watching all of your videos this semester, so I'm prepared ha :) You're the greatest. Eventually going to join your channel. Worth every penny!
Just happy to be able to help you out Neiko!!!
@@brianmclogan I need help. I take Algebra 3-4 and I'm asked what is a reference angle and when I take your definition it don't help
i dont understand
Bruh, he's just explaining it in a more complex way. Just look at the denominator and your good. No need to worry about the process
Nathan 4173 yes, I agree, this dumb areal idoit is some fkn crap
thanks
