1. Explaining how to obtain get the phi!

Chronology of Phi :

Firstlty, research of about phi is Archimedes by using circle which have diameter and to count/calculate circle by making polygon. Afterwards we can count/calculate the perimeter from polygon of exist and about circle with the side twelve,twenty four , fourty eight, and ninety six . And finally we get the boundary from nearer value phi, that is among between two hundreds twenty three per seventy one and twenty two per seven or can be writed by three poin fourteen.

2. Explaining how to obtain get the formula a,b,c!

To obtain get the formula a,b,c that is by altering / manipulate the square equation become the perfect square, among other things :

a) Alter the coefficient of x square become one.

b) Eliminate constanta in internode left(two equation is joint minus c per a).

c) Enhance second is joint of square half from coefficient x.

d) Alter the left internode become the perfect square.

3. Explaining how to look for wide of area limited by y=x2 and y=x+2!

To obtain get a wide of area from two equation, we have to know the second boundary of that equation. To get our boundary have to equalize second of that equation, that is y one is equal to y two. x square is equal to x plus two, hence x of square of min x min two. Afterwards we get its boundarys that x is equal two and x is equal to min one. After we get its boundarys, we are second integral of equation with of way of y one min y two. Becoming, wide of area limited by y is equal to x of square and y is equal to x plus two is two

4. Explaining how to determine the trapeze volume!

To obtain get the our trapeze volume have to know the radius and high of the trapeze. After we obtain get fingers is we can look for wide of pallet from trapeze that is a circle. With the our formula phi dot r square will get the broadness. To determine the our trapeze volume can use the formula of one per three dot pad broad dot high.

5. Explaining how to prove that in any trilateral hence sum up its angle;corners 180⁰!

Firstly, we make trilateral any through/ passing one of side at parallelogram and that trilateral have to congruen,with that will be formed to by develop build to level off the parallelogram. Fourth amount of angle corner of parallelogram is three hundred six degree, because parallelogram formed represent the merger two triangle which congruen, with that sum up the angle corner from each trilateral is one hundred eighty degree. With that sum up from third angle corner of trilateral is one hundred eighty degree.

6. Explaining how to determine the probabilitas appearance sum up the number of bigger than 6 from two dice lobed once!

We look for the number amount which possible its amount more than six beforehand that is one andsix,two and five,two and six,three and four,three and five,three and six,four and four,four and five,four and six, five and five,five and six,six and six. Obtained by twelve opportunity

, from darting two dice will yield thirty six.With that probabilitas of opportunity which possible is twelve divided thirty six. So, probabilitas appearance sum up the number of bigger than six from two dice thrown is one-third.

7. Determining how to determine the line equation which is [through/ passing] ( 10,0) and touch the circle x2+y2=9!

Firstly, we alter the radian equation become the x of square of plus of y of square minus nine is equal to zero, c=minus nine. Hence direct us can use the formula x multiply the x one plus y multiply the y one plus c is equal to nol. Coordinat ( ten poin zero) we make as x one, y one. its Tangent equation ten x plus of zero times rill y [of] [is] equal to Nine. Becoming, it’s line equation ten x minus nine is equal to zero.

8. Determining how to determine the theorem Pythagoras!

To determine the our theorem Pythagoras have to take example beforehand with draw the right triangle and have two from the right triangle side. After we obtain get, its both sides or its sides comparison, we can look for it with the square oblique side is equal to second square sum up its side.

9. Explaining how to look for the anomalous number amount 200 first!

To obtain get the anomalous number amount two hundreds first if we use the way of traditional very hard. To facilitate, we can use the theorem of line and row. To get we can use the formula Sn of equal to ½ n multiply the a of plus Un.To get Un we can calculate the U₁,U₂, and so on and determine the difference. Afterwards Un will meet by including a plus ( n minus one) dot b. Un is equal to two n min one. Because anomalous number two hundreds first, hence Un is equal to two hundreds hence its result three hundred ninety nine. Becoming, anomalous number amount two hundreds first is fourty thousand.

10. Explaining how paint/ making cube knew [by] its flanks!

We paint the frontal area beforehand, then make the angle of deviation withdraw. From each our angle corner dot get the area frontal and we make the side orthogonal, big of inclination according to angle corner with draw. Hence by connecting each our dot get a cube.

EPISODE RASHER OF MR. MARSIGIT

At young old, Mr. Marsigit is a diligent, his friends only pass the Senior High School he can pass the strata 1. After passing strata 1,he is studied in London, English. Over there,he is represent the Indonesian choice student to learn foreign. A lot of matter which acquisition of when in London, He has a belt which possible in Indonesia there no. Others still a lot of experience which he get the time study in English.

Nowadays Mr. Marsigit have passed the strata 3 and have pride of place in Yogyakarta State Universitty. As student we shall be grateful to also have the experienced teacher. His Experience shall become our reference to more achievement in so many matter. If our desire why don’t.

Not yet this old, Mr. Marsigit compile a book of mathematics Junior High School by basic English language which its contents very captivating of reader to be diligent learn. Besides us can learn the mathematics perhaps we also can learn the to have Ianguage inggris. One of its contents which he is explain that is hit the linear equation and kuadratic equation. For the equation of our linear enough know the existing variable. And then, the our square equation can look for it with the factor and or with the formula abc. To use the our formula abc have to know the deskriminan from the square equation. There is three kinds of form assess the deskriminan, that is :

1. If D>0 hence proportioned parabola in two dot representing its solution gathering

2. If D=0 hence proportioned parabola in one dot.

3. If D<0 hence parabola is not proportioned.
