Yummy Pi

Pi (π) is all over the universe!

Pi (π) ❤ circle
circumference = 2 x π x radius
area = π x radius ²

March 14 is yummy Pi Day! The constant π (Pi) is all over the universe because of the circle. Have you notice, that things in the universe moves in circles. & when there is a circle, there is Pi.


بسم الله الرحمن الرحيم
وهو الذي خلق الليل والنهار والشمس والقمر كل في فلك يسبحون
It is He Who created the night and the day, and the sun and the moon,
all (the celestial bodies) swim along, each in its rounded course.
[Holy Quran 21:33]

ماشاء الله the sun & moon swim along (يسبحون)
each in its rounded course (فلك) - it's so true ☼

OK so take challenge 1 : add up 1 + 2 + 3 + 4 + 5 until 100

It's difficult? It's easy! 1+100=101, 2+99=101, 3+98=101, 4+97=101, 5+96=101...
First number (ascending) + last number (descending) always gets 101. This is until 50+51=101.
So 50 x 101 = (50 x 100) + (50 x 1) = 5000 + 50. The answer is 5050.

challenge 2 : 16 x 181
calculate by power or 10s

16(100) + 16(80) + 16(1)

= 1600 + 1280 + 16
= 2600 + 280 + 16
= 2800 + 80 + 16
= 2880 + 16
= 2890 + 6
= 2896

So, there's repetition in adding up from 1 to 100...

Anyway... I still remember back then, there was so much mathematics. When I was 8, my class teacher won't let us go back home until we answer the multiplications correctly. At 9, I was looking at a senior math book & was excited to see divisions. At 10 we learn fractions. 14, trigonometry. 16, algebra. 17, functions, integral.

∫ f(x) dx
yes my national school teacher taught me this in Malay
it is called kamiran, taught in matematik tambahan
so if you're high class educated, explain this (◠v◠)v
Then, in university... we built applications which draws circles, curves, spheres etc to model objects. & even when drawing curves P(u,v) = ∑ ∑ Bi,n(u) Bj,m(v) Ki,j there are repetitions - this symbol ∑ means repetition. Yes repeat it again & again, but not till infinity ∞.

Ohh I think I'm hungry now. A pie seems delicious. (◠9◠)
