I am here because of my exame on exame
Tnksss I have an ass this helped me a lot
Feeeeeeeeeeert!
I beacom a topper in a class thanku for helping
🙏👍
Finally got the right video
i just realized my math teacher used this vid and added a voiceover
lol
tnx
Excellent 👌👌👌, teaching also ur videos making is perfect and fantastic Madam.
The Ratio between the Circumference and Diameter of any Circular objects like Small Ring to Big Moon always is π (Pi)…
For example, Take a small Ring.
Using thread measure it's Circumference (C)
and Diameter (d).
Now,
C/d = one answer in Numbers….
Next imagine you are measuring Moon Circumference (C) and it's Diameter length. The ratio is:
C/d = gives the same answer in number what we got in the case of small Ring.
Conclusion:.
C/d = Same number every time…
That same number is π….
C/d = π .
So the circumference of a Circle formula is C/d = π
C = πd
C = π (2r)
C = 2πr units…
Pi is the 16 th Letter of Greek Alphabet…. Almost maximum Maths Symbols we are using is Greek Language Letters….
Difference Between Rational and Irrational Numbers:
Rational Number:
It has Non-Terminating and Repeating (Recurring) places of Decimals.
Example: 10/3 = 3.33333333…
22/7 = 3.142857 142857 142857…..
Irrational Number:
It has Non-Terminating and Non-Recurring places of Decimals.
Example: √2 = 1.412135623
π = 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679 …
Hence Real Numbers = The Set t of Rational Numbers + The Set of Irrational Numbers…
Thank you so much i now started learning all this and this video is very helpful
Wooooo
Nice!!!
Nice video helped a lot 👍
Tomorrow is my exam I hope this helps me 😸
What is surds
Bhakkkk

because of this channel i am the best in this class
Bravo! You've been a great teacher of mine and have thaught me this concept well.
what about terminating and recurring decimal numbers?
hey
Help i'm in 5th grade and i'm the most stupidest child in there .
Really don't memories
Noob uploading 10 video for a single concept
You saved me on a test,you'll be a school teacher ان شاء الله
Yes I love this chanle
Verry useful vidt
