1. Terangkan bagaimana memperoleh bilangan phi.Closely allied to the quadrature problem is the computation of phi, the ratio of the circumference of a circle to its. By successive aplications of process, starting with the regular inscribed and circumscribed six-sided polygon, we can compule the perimeter of the regular inscribed and circumscribed polygon of 12,24,48 and 96 sides, in this way obtainins ever closer bounds for phi. This is esssentialy what Archimedes, fanally obtaining the fact that phi is between 223/71 and 22/7 or that, to two decimal places, it is qiven by 3,14. 

2. Terangkan bagaimana memperoleh bilangan a b c. 
Step by step : 
• Change coefficient x become one 
• Eliminating constanta of at laft internode ( the joint lessened by c/a ) 
• Enhancing the joint with the square of semi from coefficient x 

3. Terangkan bagaimana mencari luas daerah yang dibatasi y = x2 dan y = x + 2. 
For the first searc the intersection point of the both of curve that is in point (negative one, one) and (two, four). Both of the equation have been integral that is curve on the top minus curve which in underof it., so that it's area can be find from integral x plus two minus x square equel a half x square plus two minus x to the power of third with negative limit one until two so that its area can be count that is four comma five units area 
4. Terangkan bagaimana menentukan volume kerucut. 
If known a cone with radius of its base is r and its altitude is t, so that to find the volume of cone equel the area of base multiply the altitude where it’s area of base is a circle, so that the volume of cone is equal to phi multiply radius square multiply altitude. 

5. Terangkan bagaimana membuktikan bahwa dalam dalam sembarang segitiga 
  Proof:
For the first, make a scalare triangle, making lengthening of lines from whatever point. Here, for example point of C collinear with AC. Then, through the point of C, make a line which parallel with AB. 
The corner of DCE is equal to the corner of CAB because it’s facing.
The corner of BCE is equal to the corner of ABC because it’s opposite.
The corner of ACB plus the corner of BCE plus the corner of ECD be located in one line is equal one hundred and eighty degree, so that the corner of ACB plus the corner of ABC plus the corner of CAB is equal to one hundred and eighty degree.

By using opportunity, sum up the number more than six from two dice which lobed once there are twenty one, so that the probability of number appearance mare than six is twenty one devided thirty six.

7. Terangkan bagaimana menentukan persamaan garis yang melalui (10,0) dan menyinggung lingkaran x2 + y2 = 9. 
line equation which is through in point(ten, zero) with the radius is three, to determine by x multiply ten plus y multiply zero equal to three square, and then the line equation become ten x plus zero equal to nine, then x equal to zero comma nine.

8. Terangkan bagaimana membuktikan dalil phytagoras. 
for example a b c represent the side straighten and hypotenuse from right triangle, at two square which is each by a plus b as a sliced. The first square sliced become six shares, that is two squere its sides and four right triangle which congruen trilaterally is determined. While squere is secondly slides to become five shares that is square hypotenusa and four right triangle which congruen trilaterally is determined . integer a b c deputize the foot and right triangle hypotenuse. Three the number known as by triple phytagoras. And then to look for one of the number a b c that is hypotenuse square equal to square from bevel side which is one plus square from other bevel side, earn is also conceived by teorema phytagoras.

by using series of arithmetical, the first terms equal one, whit different two and there are one hundred terms, so that sum of add number two hundred first equal a half of one hundred multipled two multiple first of terms plus terms of hundred minus one multipled two , a result equal ten thousand.

10. terangkan bagaimana melukis atau membuat kubus yang diketahui rusuk-rusuknya.
example, will made cube ABCDEFGH, with bsae ABCD and side right are AE, BF, CG, and HG, length of side is five centimeter, angle of deviation is thirty degree, and proporsition of project equal two fifth.
• Drawing line Ab five centimeter with horizontal 
• On point of A, point angle of deviation thirty degree, Ad is line orthogonal, because length of project is two fifth so that length of ADequal two centimeter
• Project aslant of square ABCD us parallelepipedum, so that base can finished
• Centre of side is vertical line, so point of angle EFGH can be drawn, then cube of ABCDEFGH shaped.
