### Mathematics Blogs

I was very very busy that I seldom visit my blogs. However, I am very happy and thankful that although I was detached, people online continue to visit and follow the blogs I have made. That is very fulfilling for me. Thank you very much!

Here are the list of my other blogs aside from Mathematics Realm:

1) Learn at Mathematics Realm
This blog is continually developing. It is intended to help students and educators on basic and advanced concepts in Mathematics.  It provides information, lessons and tutorials on specific topics from different areas of Mathematics.

2) IGCSE at Mathematics Realm
This blog is for students who are taking Cambridge International General Certificate of Secondary Education (IGCSE) or O Level Mathematics. It provides illustrations and detailed solution of IGCSE past paper items. Items are of varying difficulties.

3) CIE Math Solutions
This is my youngest blog. It aims to include all Cambridge International Examinations (CIE) Mathematics. Some of them are Cambridge IGCSE Mathematics (0580), Cambridge O-Level Mathematics D (4024), Cambridge Additional Mathematics (4037 or 0606), and Cambridge AS and A Level Mathematics (9709). All items are from past papers with full illustrations, calculations and explanations.

### BEAUTY OF MATHEMATICS 5

 Notre Dame Cathedral, Ho Chi Minh City, Vietnam
The photo aboe is taken at the Notre Dame Cathedral located at the downtown of Ho Chi Minh City, Vietnam. This is just one of the photos I have taken when I was there. This is actually the side part of the cathedral.

The cathedral, depicts architectural symmetries, both inside and outside. The windows and doors are perfectly placed that adds to its aesthetic value. The presence of circles and curves perfect aligned added with very intricate details gives an excellent texture to its beauty.

Make me wonder, how many windows are there in the cathedral? I did not have the chance to count them all.
With its intricate details, the cathedral was constructed between 1863 and 1888. How many people worked for the construction of the cathedral?

What do you think?

### CONNECTING DOTS WITH LINES (PART 2)

This is the second part of the the post Connecting Dots With Lines. In the previous post, the solution of the puzzle of connecting nine (9) dots with four (4) lines only was shown. Possible and common wrong answers are also shown with corresponding reasons why they are not the correct solutions.

This time, it involves twelve (12) dots. Your goal is to connect all of them by using five (5) lines only without lifting your pens, without retracing - the last segment must stop at where the first segment started. (Hint: You can cross another line.)

Can you do it?

### BEAUTY OF MATHEMATICS 4

 The Technohub, Quezon City, Philippines
The photo above is the 3rd of the photos taken at The Technohub located at Quezon City, Philippines.  The fountains depict a common mathematical graph, which is the parabola. In Physics, it is called the projectile.

The amount of force needed to push the water upward is very important in determining the height of the fountain. The greater the force, the higher the fountain is. The varying heights of the fountains contribute to the beauty of the facade of the park.

### BEAUTY OF MATHEMATICS 3

 Technohub - Quezon City, Philippines
The picture above is also taken at The Technohub in Quezon City, Philippines. It portrays the use of spheres as part of the facade of the park. They add more mathematical aesthetic together with the curvature formed by the establishments around it.

The spheres used vary in sizes. Can you approximate the diameter of each? How about their volumes?
