    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.

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

      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

      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!

All these topics are illustrated by diagrams/shapes and old fashion Formulas. The Formulas can also be derived using basic and Advanced Mathematics.

    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.

    • @jaydonkurian2593
      @jaydonkurian2593 4 роки тому +10

      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 :)

    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
