Hey guys, here's a cool study tip: watch these BEFORE the teacher's lesson. This is because, when you watch this before the lesson you get a nice idea of what's coming up and you will be less intimidated. You can also understand the teacher better since the teacher will probably be going at a faster pace whereas here, you can pause and process info. This is great for people who can't focus/understand stuff in class.

[@Andresseus]

Truly agree, you can't just tell me pi is equal to 3.14, I need to know where that number comes from.

[@starbrightgalaxy3962]

i do it bc we get a homework pass ifwe catch a mistake by the teacher

[@bluefox481]

We got this lesson in our summer book while we didnt take it yet, they didnt teach it to us bcz the covid 19 while they needed to teach it for us, so im working on ur tip for watching it before school come back and review it for us

[@frezywizard]

They don't tell us what they are going to teach us before they start to teach us

[@Awesome-1001]

Heres another cool tip. To know if you are dealing with any special right triangle: Take the shortest leg (ex. =3) Then square it. And divide by 2. 3²=9 --> 9/2 =4.5 (add and subtract 0.5 aka +-) 4.5 + 0.5 = 5 , 4.5 -0.5 = 4 Now you know youre dealling with a 3 4 5 triangle Another example for sport. 7² = 49 --> 24.5 +- 0.5 --> 24 , 25 Triangle 7,24,25.

Hello! It might not reach you due to the overwhelming comments you receive throughout all your lecture videos, but I wanted to take the time and thank you for providing so many educational videos, you have no idea how much this is helping me, it will even help me get through college. This is not much, I know, but remember that you have helped so many, and without you, many wouldn't be where they wanted to be (in terms of careers and education) Don't ever stop making more videos!

[@kunashemhuka9292]

This is how you teach mathematics and how it's suppose to be broken down thank you so much wow!!!!

MR. Organic Chemistry Tutor, thank you for another incredible video/lecture on Circles in Geometry and the Basic Introduction to Areas, Circumference, Arclength, Inscribed Angles and Chords. All these topics are illustrated by diagrams/shapes and old fashion Formulas. The Formulas can also be derived using basic and Advanced Mathematics.

Im a visual learner, like i legit cannot understand if the teacher is just explaining it rapidly and stuff, and here, it really helped me out, im doing my final exam tomorrow and this was the only concept i didnt understand until now, i got to see it done, while explaining and examples , and i dont hear like "get it now? ok so now you try" its more like "ok we will do this together"

It’s important that you divide θ by 360° when calculating properties of a sector, not by 360 radians. Always include the degree sign to avoid confusion.

Good morning sir, please I have a correction to make at 17:21 625pie is 2057.7 and when you minus 336 from 2057.7 the answer is 1721.1 Thanks

are you resident obama daugther

Umm... how?! I just checked and 625pi does equal to about 1963.5, the thing is you probably typed 655pi which will be equal to 2057.7.

[@merceditaamion8784]

3:26 wait wait, where did the m from mac come from???

[@jaydonkurian2593]

the "m" in mAC means measure of the arc AC. This m is often used when writing the "measure of" angles, arcs, etc. For example, mAB is read as the "measure of arc AB". Or if you were talking about the measure of an angle, you would see something like this: mABD, read as the "measure of angle ABD". Hope that helps :)

When calculating the area of the hatched region at 14 minutes into the video, aren’t you forgetting to subtract out the area between the arc BC and the base of the triangle?

[@starryasteria9166]

im starting to think this guy iz a god

[@TaliaAlsayed]

in 8:02 why did you write cm^2 and not cm only? we did that for the circumference, so why not the area? is it because the formula has a ^2?

[@malliemaile6746]

I had the same problem as you but remembered that rarely anyone presents an area in a straight line but in a square. That's why, cm²

on 8:56, why'd u write 2piR not 2piR^2?

[@doggy3327]

I'm late but review the difference between the formula for the area and the circumference of a circle. The circumference is 2piR and the area is piR^2

[@AlbiniaYT]

3:29

[@mukorodiana573]

The area of the circle given in the example, isn't that the area of a sector? It's quite confusing.

[@Andresseus]

At 9:30 you could've just said "Multiply the percentage the angle occupies in a 360 degree circle, with a circumference of 43.96." 150 Degrees is 41.6% of a 360 Degree Circle that has a Circumference of 43.96. Multiply .416 by the circumference 43.96 BOOM You get an Arc of 18.28736 Round.
