Imjingak

I went to Imnjingak in Paju from Seoul.

Adress : Imjingak, 177 Imjingak-ro, Munsan-eup, Paju-shi, Kyeonggi-do, Korea

Phone No. : 031- 953- 4744

Beopgi basin

I went to Beopgi basin in Yangsan, Kyeongsangnam-do, Korea.

It would be hard to go by public transportation so I recommend taking by your own car.

It has parking lot.

Basic Information about Beopgi Basin

Adress : 340 Beopgi-ri, Dong-myeon, Yangsan-shi, Kyeongsangnam-do, Korea

Phone No. : 055-383-5379

If you want to go by public transportation, I can tell you 3 bus stops near Beopgi basin.

1. Changi Maeul (창기마을)

2. Beopgi Maeul (법기마을)

3. Gaegok (개곡)

They would be far from Beopgi basin. 

Distances from the basin are about 0.5 mile~1.4 mile ( about 800m ~2.3km ).

From Beopgi Maeul ( 법기마을 )

From Changi Mael ( 창기마을 )

From Gaegok ( 개곡 )

Pictures about Beopgi Basin

Many tall pine trees are in the park with Beopgi basin.

An interesting pine tree

The basin.

What's in that structure? haha...

A hand monster is approaching to the door!

Green's Theorem

1. Setting

[pic 1]

Let a closed curve C be set on x,y plane.

Domain D is covered by closed curve C.

[pic 2]

Let's functions, M(x,y) and N(x,y) exist and they have partial derivatives on D.

The formula can be notated like it in [pic 2] on C.

[pic 3]

This formula can be divided like [pic 3] 

because M(x,y)dx and N(x,y)dy are on same closed curve C. 

2. Induction

2-1. Considering The Formula at X Coordinate

First, we consider the formula in [pic 2] at x coordinate.

[pic 4]

[pic 5]

We set a domain like a formula in [pic 5].

[pic 6]

So, result is like [pic 6] on x coordinate.

2-2. Considering The Formula at Y Coordinate

Next, we also consider the formula in [pic 2] at y coordinate.

[pic 7]

[pic 8]

We set a domain like a formula in [pic 8].

[pic 9]

So, result is like [pic 6] on y coordinate.

3. Conclusion

[pic 10]

We can combine same domain.

Therefore, we can prove Green's Theorem.

I usually eat cereals as breakfast.
