Big props for your 3 individual videos on the uniit circle. A lot of these videos on memorizing the unit cricle were craming all these numbers in a 10 minute video and I was honestly getting overwhelmed. Clicked on your video and I was slapping my face on how obvious some things were. You explain things so clearly! Thank you.
You’re welcome! It’s a rich topic. One of my favorites to teach.
I just turned 13 and love math. Trigonometry is a subject I was trying to grasp, specifically the unit circle. This video is actually so good at explaining the unit circle and teaching about radians, and plotting coordinates with it. I finally can jump to the next step in trig and start learning how to graph sine and cosine graphs. 😁
Thanks! Have you watched any videos that show graphs of the functions as “unrolling” the unit circle? I haven’t made one yet.
@@doesmathforcoffee Yes, and I am starting to get the hang of graphing trigonometric functions.
Thank you so much! My teacher wasn’t explaining this very clearly and we have a test coming up, so I found your video and it made perfect sense! It was so clear and concise. Thank you!
Glad it helped!
Beautiful presentation - I watched all 3 videos for a quick refresher!!! When I was in school, I never memorized the unit circle and all the coordinates...I just got really good at right triangle trig, and I could figure each problem out as I went. That is why I greatly appreciate your approach, which explains the "how to" and the "why" instead of just giving the values. I'll be referring you to my students for some quality tutorial videos!
Thank you! I taught geometry several years before I taught trig. Special right triangles made sense of it.
i can’t thank u enough for this god bless you ❤
Thank you!! Grateful to be of help.
At 6:50 point (1,0) is Mislabel as point (0,1) so guys if you using this as a reminder make sure you don’t confuse the point👍
You're a brilliant woman and I appreciate you
Thank you and thanks for watching!
Where are all the views to this video. RUclips just recommended this to me, so I hope they start recommending it to all the others searching & looking at videos about the triangle.
I've watched a lot of videos about the unit circle & special triangles, but this is the first one combining both in one video. You did an awesome job here & I really hope a million other people get to see this video very soon.
Thank you! I’ve always taught the unit circle with the special right triangles. Makes it easier to learn, IMO.
Really clear explanation, amazing presentation. Thank you
Thank you!! Time-consuming, but those unit circles were fun to make.
@@doesmathforcoffee The video will help a lot of students, your channel is starting to grow exponentially 😀 so the content is reaching more and more people.
Exactly what I needed thanks
Glad I could help
These Unit circle videos you made are the best on youtube! Was struggling before, but it's actually so simple wth.
Thanks! Unit circle was one of my favorite subjects to teach.
EXCELLENT
Thanks!
How to find the center of a radius. With given radius and one coordinate?
I'd use the midpoint formula. (x1 + x2)/2, (y1+y2)/2.
Are the coordinates at 6:56 correct? Seems like the 60-degree angle coordinates need to be reversed.
Cut & paste typo. Not worth pulling the video down. Let’s pretend I did it on purpose to test you. 😉
@@doesmathforcoffee great video, very helpful. Just wanted to make sure (:
Thank you!
how do you know the hypotneuse is 1 based off the radius
The unit circle is defined as having a radius of 1 unit and the hypotenuse is a radius of the circle.
thank you so much you are way better than my math teacher. Better explanation than my own teacher. You just saved my math grade. 😭😭😭😭
Glad I could help!
Saving lives!! 🔥🔥thank you
LOL! You’re welcome.
This is all my teacher has to put on and I’ll understand it all
You must have done well in geometry?
Tammy is the goat 💯
Thank you! Hope my students see your comment. ;)
My new fav account!!🤩🤩
You like math? Cool. (Like your frog profile pic.)
great video. i just watched this video and i don't know what i would use it for🤣🤣🤣🤣🤣😂😂😂😂😁
Thanks! Made this for trigonometry students because they are usually required to memorize the unit circle. I agree that people not in that class don't need it.
I think there's a slight mistake at the very end of the video when you summarize all the concepts. For coordinates, the 30 and 60 degree coordinates are the same, it should be inverse, no? Thanks!
Not surprised I made a typo. When I made these last year, I was in a hurry to get them uploaded for a friend’s class. Let’s call it “extra credit” if someone finds the mistake!
@@doesmathforcoffee Haha thanks for clarifying!
Nice, but how can I use this in my life for example?
LOL! Take a trigonometry class in real life. You’ll need it then The real answer is that trigonometry is about advanced math functions that describe how some things work in the natural world. Electricity, physics, etc. It's a prereq for calculus - which is when the really cool stuff happens.
well, I have something to apply it on, but for me it is new, so... I need to understand it therefore more.
If I see how it is applied on an example, I can understand it better imo@@doesmathforcoffee
OR...
Can I e-mail you private so I can explain the purpose?
Damn... u mean you were here all along 😭
😂
We are going to recite this tomorrow😭.
Hope this helped you memorize everything!
you made an error in the cooodinates at the end
Yes, I know about that typo. Let's just call it "error analysis".
am I the only one that got confused asf when the final coordinates of the unit circle came up? Like that's just definitely wrong
Made a typo on one of these videos, but if you can spot it, you’re not confused asf. You learned it.
Great video, but the coordinate summary at 6:48 is (respectfully!) a bit of a mess 😅 The coordinates for the 30-60-90 triangles are backwards (so some signs would have to change), and the negative in front of the x-coordinate at 330 degrees has to go🙃 Really well done, otherwise 🤘
Advantage of teaching over being a solo video creator is that I have about 30 “editors” checking my work in class if I screw up. If they are really good ones, it’s a teaching moment. If they are really dumb, I demonstrate how to find them, fix it, laugh it off, and move on. Sadly, RUclips doesn’t allow for the edits necessary. I’d have to pull the whole video down. Figured smart kids would get the big ideas anyway. Not the first or the last math mistakes I’ve made in public. Good catch.
@@doesmathforcoffee That's a great way of looking at it :) I would encourage making the changes and putting the video back up because the rest of it is 🤌 I was doing a refresher for my calc III class and I definitely had a "...wait...something's not right..." moment lol, and confirmed it like 4 times to make sure I wasn't just seeing things before commenting lol.
See? Unintentional teaching moment. YOU checking it as a student is more useful than this 62 year old busy teacher stressing about being perfect on RUclips. Can’t just replace a video - when it’s deleted, all the views and watch hours are deleted, too. I will probably edit the description at some point. We just started our second semester this week, so my kiddos need algebra and geometry content right now. Good luck in Calc III! What degree program are you working on?
@@doesmathforcoffee Oooooohhhhh yep that would be more views than I'd be willing to lose lol. I'm a mechanical engineering major in Florida and I'm pretty much swimming in calculus and physics classes these days 😵💫😅 I hope the kiddos don't give you too much of a hard time this semester!
