The art of decimals

If you remember with my other post about the number. We can look at the formula like this:


  1. (1/4)1 + (1/4)2 + (1/4)3 + (1/4)4 + (1/4)5 + . . . . = (1/4)+(1/16)+(1/64)+(1/256)+… ≈ 1/3

  2. (1/3)1 + (1/3)2 + (1/3)3 + (1/3)4 + (1/3)5 + . . . . = (1/3)+(1/9)+(1/27)+(1/81)+… ≈ 1/2
  3. (1/2)1 + (1/2)2 + (1/2)3 + (1/2)4 + (1/2)5 + . . . . = (1/2)+(1/4)+(1/8)+(1/16)+… ≈ 1/1 ≈ 1

So, how about the Art of Math? So Beautiful?? enjoy your day

This Math Exercises, please don't try this at home

Do you ever see the number operation like that? You will see that the result are TRUE with the Wrong way.. Oh shit, don't try this to the other number. OK? hahhahaaa




Please call your teacher to solving the problems!! So, this is some guarantee that your teacher will come to HEADACHE

The circle and the rectangular



Please see at the two pics above. This picture are courtesy from http://bimosaurus.wordpress.com/2010/04/29/lingkaran-dan-persegi-panjang/ . At the first picture show that the circle will be cut as eight pieces congruency. And the part of pieces A and B will assembled as the picture. So we can see that the assembled side will looked like RHOMBUS.

At the Pict 2 we will cut the circle many pieces, nd will assembled as the picture. We can see that the space will look like rectangular space. So, we can determine the formula of rectangular from the circle formula. If the large of circle is (22/7).(r^2), so we can count the wide of "rectangular". Wide = large/r.

The Other Art of Number

Please check and think about the numbers below. There is some *arts* to make the mathematics are beautiful. The limits of quarter whit exponential 1 and etc, will reach 1/3. 1/3 will reach 1/2, 1/2 will reach 1/1. So, Please note it whit th

  1. (1/4)1 + (1/4)2 + (1/4)3 + (1/4)4 + (1/4)5 + . . . . = (1/4)+(1/16)+(1/64)+(1/256)+… ≈ 1/3

  2. (1/3)1 + (1/3)2 + (1/3)3 + (1/3)4 + (1/3)5 + . . . . = (1/3)+(1/9)+(1/27)+(1/81)+… ≈ 1/2
  3. (1/2)1 + (1/2)2 + (1/2)3 + (1/2)4 + (1/2)5 + . . . . = (1/2)+(1/4)+(1/8)+(1/16)+… ≈ 1/1 ≈ 1

The Error Number

Now, I will share to you about something that will happened in Mathematics. Please see and think about it:

x = 0,9999999
10x = 9,999999
10x – x = 9,999999 – 0,9999999
9x = 9
x = 9/9
x = 1

Now, We will know.. That the after point decimals are DANGEROUS to neglect it.. So, please rethink about your DECIMALS Approach to make some match result!!
