I learned the unit circle and the equation in 2 seperate chapter in school. This is the first time i've seen the connection between these two. Haven't thought much about that "sin^2 + cos^2 = 1" as the circle equation. It really opens up my mind.
Really good stuff here. I find it important to be able to identify a circle or a family of them, and these videos are going to help us a lot with it. Thanks, teacher.
@@pinklady7184 i didn't learn this in school unfortunately, and I just realised it was a topic within the SAT (funnily I'm learning calculus but they don't teach the equation of a circle? I don't even know) :) all is well anyways since the video's up and I got every question about equations of a circle right so far, thanks for your concern lol
Vanessa Lam I am surprised you haven't learned that in your school. I am from Ireland and our educational system differs. I had learned all those things in school and they were all covered by our teachers. Then a month or two before exams, we had time for revisions. That was a long time ago. Today, I am just relearning maths as first a hobby. I'm doing the same with other studies, though I am not in university. I am self-teaching from books and videos, so to save money and avoid college debts. I ask students & graduates what materials they study in universities, so to prepare myself. Then I study them at home. I'd go to university only when I am good and ready, well-prepared and skilled up beforehand.
Vanessa Lam, if you are unsure about equations on graph, check out www.desmos.com/calculator. There, you can write equations and watch answers on graphs. Watch Desmo tutorials. They take only few minutes to learn. You can learn equations fast by playing with a calculator. Put in random equations, press return and watch the graph.
@@pinklady7184 That's great you're doing that, and I think what you're doing is right! The internet is an infinite resource and we should all be grateful for access to it. I still think you're misunderstanding something here haha, I'm still 2 years away from college so I think they may teach this to us next year. I take the IGCSEs through my school and we cover calculus but just not equations of a circle, I suppose. I'm not that worried for myself anyways, since this would be the first time I take the SAT and its mostly just for me to get a feel for the test and properly introduce myself to its contents, since I want a decent score for it to apply to US universities. My school does not require all students to take the SAT, heck, it doesn't tell us anything about the contents of it, so I'm self studying everything new on it! Which is why I'm turning to the internet. Maybe my school would teach this concept next year, who knows, but I'm glad such videos are available online so I can properly learn the material :)

as others have said exam season is approaching fast so could you just bulk upload any lessons you have recorded?
I need part 3 and 4 rn! lol
My math 2 teacher just gave us the equation and said this is the formula for a circle
same lol
I know nothing about hyperbolas but I know about the equation of a circle. I feel smart but not at the same time
That clock 🕰 on the wall is broken
help please update soon!! i need to catch up with equation of a circle for SAT in 2 weeks XD
You should have studied that ages ago, instead of leaving everything to the last minute. I'm sorry that happens to you.
