1. Explain how to get the numeral of phi ?
The area of the circle is equal twenty two with diameter is equal seven. So to arithmetic of the phi is the circle of area divide diameter.
2. Explain how to get formula of a,b,c ?
The method to get the formula of a,b,c. The first is altering coefficient x become one, than eliminating of at left node than an hence second is joint with the square of semi from coefficient x than altering left inter node become the perfect square.
3. Explain how to look for of area y = x2 and y = x+2 ?
First look for crosscut dot both of the equation. Than to get the absis from both of the equation. Than to used to limit integral. And first equation to negativity second equation. To get area then we must calculate from of integral
4. Explain how to determine the volume trapeze ?
Have been known that trapeze volume is equal to wide of high times, riil pallet. Where wide of its pallet is a circle. The area of the circle is equal phi multiply real square radius. Then trapeze volume is equal to phi multiply the high times, real pallet
5. Explain how to show that into the triangle any, then the amount of its three angle is 180 ?
First make in any is triangle. Than we cut that triangle become three participation. Notes don’t cut in the angle. And each an angle we sheaf in one dot. Then we get angle one hundred eighteen degree.
6. Explain how to get probability the amount number than more six from two dice that throw once ?
By using opportunity hence possibility emerge from two dice is thirty six. Dice amount more than six there is twenty one possibility. Hence opportunity emerge two dice with the amount more than six is equal to twenty one divided by thirty six.
7. Explain how to get equation line what is through ( 10,0) and touch circle ?
From coordinate ( 10,0) and touch the circle of x square add the y of square equal nine, where nine representing radius and x of is of equal y represent the index. become the its line equation ten times x and zero times, rill of y equal nine. And become ten x negative 9 equal of zero.
8. Explain how to get Pythagoras ?
Taking example right triangle with the dot A,B,C. By AB represent the side straighten and BC determinable hence Pythagoras. With square of is equal to side square straighten in adding side square level off.
9. Explain how to get the amount of numeral strange first 200 ?
By using arithmetic, valuable first tribe one differently two and from one hundred tribe. Hence sum up the anomalous number two hundreds first is equal to half multiply one hundred multiplied by the added by first tribe of tribe to one hundred lessened by one in its two result times, rill is equal to ten thousand.
10. Explain how to get draw cube which known to flank ?
Draw the pallet flank as long as a centimeter later, then from dot of tip of that line in making angle of deviation of degree is so that formed by one of new flank as long as a centimeter multiply the its projection comparison. By accommodating us can draw the pallet from cube. Interesting of vertical line as long as a centimeter from every base angle, later then we can make the flank close cube
