Many activities in my course at Vincent Study Center....
They come as their schedule, and go home, and another students come and go.....
There are many activities :




















Listening when I teach them, practice the exercises Maths, or Physics or Chemistry....
Ask n answer....


They are discussing about math, Physics, and Chemistry....Do they exercise....

Sometimes they feel hopeless to solve the exercise....Like this photo :



After their schedule they sometime wait their parents to pick them up...
Sometimes they play jokes, listening the music from their cell phone, sometimes they tell about film, about the subjects in school, tell about music, tell about their friends or teacher whom they hate or like, tell about terms n conditions at their school, tell about exam, etc...

Closing with them, make me feel young, and know what they need, what they want, and what they think, know their world which is different with us....

Sometimes I want to laugh, surprised, and I don't know what to tell about....Sometimes they attitude so kind, so rude, not control what they say or what they do, but sometimes they look funny, georgeous, innocent and salute with their achievement.

Sometimes they no attention with exercise, blank mind, or sometimes they encourage each other...sometimes they look so tired, boring, and hopeless...
But they are our students..I must encourage day to day....

These are some photoes :


































I am explain to my private student...

That's my little story about my course and about my students.....
I'm proude to be their teacher....

When Johny, Vincent and Fanny work together, it will take them 5 days to complete. When Johny, Vincent and James work together, it will take them 6 days to complete. And when Leo, James, and Fanny work together, it will only take them 4 days to complete the paiting job. How long will it take Johny, Leo, James, and Fanny to complete the job if they all worked together...?
  2. Mr Harry brought home a bag of sweets for his grandchildren. He gave the first grandshild 2 sweets plus 1/13 of the remaining sweets. He then gave the second grandchild 4 sweets plus 1/13 of the reminder. To the third grandchild, Mr Harry gave 6 sweets plus 1/13 of the reminder. He continued the methode by giving the next grandchild extra sweets than the previous one and 1/13 of the reminder. The last of Mr Harry's grandchild took his share and found that there was no more reminder.Given that each of Mr Harry's grandchildren receives an equal number of sweets, how many grandchildren does Mr. Harry have. Also find the number of sweets each grandchildren receives...?
  3. Three men are placed one behind another in front of a wall. The men are blindfolded and told that a hat will be placed on their head taken from a bin conmtaining 3 white and 2 black hats.
  4. The blindfolder is then removed and each man is asked to determine the colour of the hat he is wearing. The third man who is furthest from the wall sees the other two men's hat and says, "I cannot tell what colur hat I am wearing." The second man who hears the third man's reply and sees the colour of the hat the first man is wearing says the same thing. The first man after hearing the replies of the other two men says, " I know the colour of the hat I am wearing." Do you know how he came to this conclusion and what is the colour is..?
  5. A man with a dog, a rabbit and a bunch of lettuce came to a riverbank. There is only a small boat that can carry the man and one of the animals or the lettuce. The problem for the man is, : If left alone together, the dog will eat the rabbit and the rabbit will eat the lettuce. How can you help the man to transport his animals and his lettuce safely to the other side of the river...?

It's just for funny....Hemmmm....Yummy...spent the time to joke with your friend....

Question This Week.....

There are two questions coming from my visitor :

1.

Tg ( p + q) = ½....(1)

Tg (p – q) = 1/3........(2)

Tg 2p = ...?

Answer

:

If : p + q = A  and p – q = B

With elimination we find :

2p = A + B

Tangen1

Tg 2p = Tg (A + B) = Gbr 1

= Gbr 2

2.

Sin (3x + 2y) = 1/8......(1)

Sin ((3x – 4y) = ¼ .....(2)

Sin 6y = ....?

Sinus1

Answer :

Misalkan

(3x + 2y) = A ® Sin A = 1/8

(3x – 4y) = B ® Sin B = ¼

With elimination we find :

6y = A - B

So sin 6y = sin (A – B)

Sin (A – B) = sin A cos B – cos A sin B

= Gbr 3

I hope my explanation make you clear and can understand.....
