What are you supposed to do if they dont tell you how big the circle is
As a math teacher, I use your videos as a resource. They are absolutely awesome. Keep up the good work and thank you for these videos. 👍🏾
Thank you so much , I finally understand how to find standard equation of a circle , I can say that Math is so easy if you really understand it.
Agreed
This was such a great explanation!!! Thank you!!!!☺️
how to determine the circle edge from the center???
i spent exactly 1 hour on how to do it coz it makes me rlly confused, now its easy because i can understand in clearly
Thank you so much for not making this so complicated
so helpful, thankyou
this was one of the most understandable math videos I have watched. Thank you very much!
Yes!
Thank you so much!!! I was overwhelmed before I watch the video.
Thanks a lot! I've downloaded the worksheet for this lesson, but I wasn't able to find the answer keys. Would you please explain, where can I find them?
Excellent, thank you!
THIS IS SO CLUTCH FOR MY GEOMETRY TEST TOMMROW TY SO MUCH SIRR😊
Thanks a lot. That really helped, now I understand
I can't understand my pre-calculus teacher because he's mic is choppy so here i am , and this is more helpful
i never been good at math. it has to be thoroughly explained to me. Is this type of math used for locating people, place, or things on maps and graphs? is it also something that is used out in the ocean- same as longitude and i forget what u call d other thing i have a headache, anyway, is that the purpose of calculus of the circle thing? im mot studying any kind of math im just curious and asking u bcus u are way smarter than me bar far 😊🙂
Thanks for making this video super easy to understand. My teacher could never do the same!
NICE EXPLN.❤
Absolutely amazing video. You are a legend.
Thank you somuch this is helpful because I'm answering my pre-calculus summative.😇
Thankyou do much❤ It is very helpful
Thanks
how did he get the radius of circle? as I've noticed, there's a small circle and big circle. how does that happened
Same question
By counting the units, you can also use the distance equation
its been a year, but I'll write down the answer for anyone else who has the same question. The radius is just the distance between the center of the circle and any point on the edge. So by counting the units from the center point out to the edge, he has the length of the radius. I hope this clears it up for someone!
after 8 year graduate, I finally understand the usefulness of this equation in computer graphic for getting a circle without using sin or pie
i like how he explain and the visuals

quantum mechanics and general relativity : lemme introduce myself
Guy deserves more likes for his service
Great 👌 lecture
Thnx sir, it helps me so much
Thank you so much for this!
I. love. you. thank you so much
God bless u💗
what is thw standard formula for circle
Where do you bring the number of r while it is not written in example
3:35 where did that circle came from??? i mean i started with a cross how is there a drawing of a circle already
I dont think the "equation of a circle" formula actually enables you to plot a complete circle, thats probably something in trigonometry. i think here its just a way of describing the circle in terms of coordinate geometry, after you know the points you can just plot the circle yourself
This is a great video, just don't get why the sigh of the seven changed in the last example
a negative plus a negative equals a positive
I was expecting from the title you would explain how the formula was derived.
one thing I don't understand if someone can help me out, what is the equation of the circle, what I mean is (x-h)^2 + (y-k)^2 = r^2, so what does this r^2 represent in the circle i.e. if r^2 = 9 what in this circle will be 9, what is the equation? what is represented with r^2? (you understand what I'm asking?)
In the equation of a circle (x-h)^2 + (y-k)^2 = r^2, 𝑟^2 represents the square of the radius. So if 𝑟^2 = 9, it means that the radius of the circle squared is 9. To find the actual radius, you take the square root of 𝑟^2 which gives you √9 = 3.
So r = 3.
So the equation would be (x-h)^2 + (y-k)^2 = 9, where (h, k) is the vertex point the radius would be 3.

Sir pre calculus notice me nag watch nako
Finally, i found this
👍🏻👍🏻👍🏻👍🏻
From 10a with love
Học đéo hiểu cái gì
Vẫn phải làm để nộp
I think my math teacher gave me the wrong video
haha
Thanks
