Amazing. I purchased your precalc and trig volume 2 downloadable lessons and I am happy to see you are still working hard today! Thank you for your hard work
In the last problem of the set you said 3.14 but wrote down 7.14 and you used 3.14 in the calculation. When you looked at the white board you expected to see 3.14 so your subconscious mind corrected what your eye was seeing for you. Just a transposition error. I have done it myself many times. You might wish to do something to correct this. Isn't it amazing how our brain can change what the light rays are imprinting on our retina and correct it to what we believe should show even when we look at the white board later. This explains why we have so many problems with truth today in communications. It explains why we get deep division in politics or interpretation of facts and stories. It explains why eye witnesses are often unreliable. It explains why we have so much division among groups of individual people. I think this is called cognitive bias and causes cognitive dissonance in individuals. What a great example for a class in psychology, composition, public speaking, Forensics, political science, religion, research, etc. I am in no way being critical of your presentation. I rate it excellent with a comment. And I am hoping someone can find a way to use this "operating experience" to help us be a stronger people and a kinder people and nation. I am glad I watched this. Now I'm going back to check myself to make sure I saw what I thought I saw. I hope you can find some way of using this valuable learning experience. ✌❤🖖
No, not a biggie. There is a message for all of us,ike when we are driving and a motorcycle or a bike or somebodies cow is on the road or an old man, like me,. I always have
An old man like me steps into the road and .y mind doesn't see anything because I don't expect to see anything other than vehicles and I hurt someone or worse or the old man in the road is me! Got to be aware always! Glad I caught it before anyone else. I make all sorts of mistakes so I know even really well prepared people occasionally make a little one. There but for the grace of God go I (or is that me?) LOL Keep on reproducing your short snapshots on math and other material. They are well done and just the right length with plenty of practice. One fact practiced 5 times. Good instructional technology. Well done.
If you go to 15:10 his mind got tripped up on squaring 7. He wrote down 7.14 because he was thinking about 7X7 then he even read & said 49 X 7.14, but his answer is on his notes, to make sure he gets the correct answer. He is human & like you said, this could be leason in itself.
@@simpleman283 Yep, thanks for understanding. I could edit out, but why do that? Its important to know that I make mistakes too and I'm human. As you outlined, I think that is exactly what happened. Thanks again! Jason
Hold up A circle that has 2cm radius will have 12.57 cm² of area,but a circle that has a radius of 2cm would fit inside a 4cm² square,so even 4cm ² of area is too much for a circle that has only cm² of radius how come that it will equal to 12.57 cm² ,I think the equation is wrong it must be √12.57cm rather than 12.57cm², so the area must only be 3.55 cm².the 12.57 cm is the circumference of the circle.
*Thanksgivings Math:* I have two pumpkin pies that are the same thickness. I want to cut them up so that each slice has the same mass (same surface area should work) while keeping the slices a reasonable portions. The answer for each pie should be an integer number of slices, meaning no odd parts left over. One pie is 12 inches, the other is 8 inches. For extra credit, include a 9 inch size.
You are the best maths teacher ever ❤❤❤❤❤❤❤❤
Agreed. 💯

Hi I use your video to teach my grand kids math ,they like your way to explain ,now they do very well in school
Awesome!
You are an amazing teacher👏🏽
my all time favorite teacher
excellent tutorial on area of a circle, thanks so much for sharing
Welcome!
math and science what the welcome for use 🤨🤨🤨
You're a good teacher.
Awww thanks!
@@MathAndScience do you have a whatsapp number i want some lessons
You are a legend teacher. I was searching for this ❤ i love how cool you explain it
You're the best teacher
Good work sir.
I appreciate your struggle.

I love your teachings❤❤❤❤
I am learning from your teaching😀 So glad I found your videos!
sir, please explain the media and the mean mode
Thank You. You Explain Better Than My School

Thanks for a great video. Very informative
A complete review of 3rd semester calculus (e.g., volumes, power series) would be fun. Ciao.
YOU are a really genius teacher!
Wonderful, thank you so much, you have cleared my doubt.👍
Thank you so very much for this video... You made this topic so easy
Hi mr.Gibson can u do a lesson about Length x Width x Height
Thank you. I am just understanding the area if the circle.
Area of circle
Where can I find more geometry videos. Studying for the ged.
Thanks from Chile
Welcome!
In the space of 1 minute I learnt more than I did in 11 years of schooling
Same here I love this man's lessons
you are genius
15:45 Love your videos. 💯
You have an error. It is not “7.14” as you’ve written. It should be 3.14
Awesome! Do you have a videos for SAT ?
Thank you. This helped because I am studying contemporary math
thank you for the lesson
Hold up
A circle that has 2cm radius will have 12.57 cm² of area,but a circle that has a radius of 2cm would fit inside a 4cm² square,so even 4cm ² of area is too much for a circle that has only cm² of radius how come that it will equal to 12.57 cm² ,I think the equation is wrong it must be √12.57cm rather than 12.57cm², so the area must only be 3.55 cm².the 12.57 cm is the circumference of the circle.
Radius is from the Center out so it’s double
My gosh your re awesome sir
What about that 3.14,l don't understand where you got it from..
Why is the last one multiplied by pie squared ?

Sir how about the volume of the pipe how to compute?
Excellent.
THANK YOU... SIR...!!!
Most welcome!
this dude is very smart
How can i know if i need to put "A"
'So, a circle, I cannot draw perfectly'
(draws perfect circle)
Makes a mistake at 15:12 (that 7.14 should have been a 3.14)
a=3.14(2 squared?
a=3.14(4)
At age of 26 i m here to study about area of circle
😂😂😂same here
ani shapes can inside the square 🤔❓❓❓
a =3.14(2 squared)
there is a mistake in 15:00
you take pie as 7.14.
No we dont
area 28.26 mm squared
a=12.56
area of circle
28.26 mm squared
radius 2 cm
(4)1 =4 (4)2=8
(3)(6)=18
why is it 7.14 X 49 instead of 3.14 x 49?
it is just a mistake
I was going to ask the same
7.14 @ 15:16
Guessing that was a mistake posed to be *3.14
a=12.56 cm squared
a=314
18+3+1+4=26
diameter 10 m
Tnq sir
circle
2+6=8
a=pi r squared
PS. The comment I was relating to was around the 16 minute mark.
4 squared
2+8=10
=16
28
Sorry. It was appx. 15 to 15.25 minutes into the lecture.
Ì am NOT expert. But... is he perhaps wrong to say that result is expressed as "cm squared"? I think it should be "square cms". Anyone??
