II. Meaning and application of difficult word

• Common multiple of 4 and 6 are number that these two lists share in common: 12, 24, 36, 48,……..

• The highest common factor divisor is useful for reducing fractions to be in lowest term.

• The circumference of a circle can be calculated from its diameter or substituting the diameter for the radius.

• Angle of elevation is the angle between the horizontal and the line of sight to an object above the horizontal.

• In geometry, the incircle or inscribed circle of a triangle is the larges circle contained in the triangle.

• In the mathematical subfield of numerical analysis, interpolation is a method of constructing new data points within the range of a discrete set of known data points.

• Many calculators and converters related to mapping and navigation.

• The representative fraction is the expression of map scale as a mathematical ratio.

• Fractions consist of numerator and denominator. The numerator representative a number of equal part and denominator telling how many of those part make up a whole.

• An equation is a mathematical statement in symbols, that two thing are exactly the same. Equations are written with an equal sign.

• Straight angle exactly 180 degrees and reflex angle between 180-360 degrees.

• Axis of symmetry, a line that divides a two-dimensional object into identical shapes.

• The quotient can also be expressed as the number of times the divisor divides into the dividend.

• A conic section is the intersection of a plane and a cone.

• Bottom margins that adjoining vertical margins are indisposed to use the maximum of the margins values.

• A cube root of number denoted x power to 3.

• The absolute value of a real number is its numerical value without regard to its sign.

• Inequality is a statement that two quantities are unequal, alternatively by the symbol <, signifying that the quantity preceding the symbol is less than the following etc.

• A vertical angle is an angle that intersects with another one. Vertical angles are two angles whose sides from two pairs of opposite rays.

• Alternate interior angles if two parallel line are cut by a transversal, the alternate interior angles are congruent.

• Corresponding angles are formed when a given transversal line crosses two coplanar lines.

• Adjacent angles is two angles in a plane which share or common vertex and a common side but do not overlap.

Mathematics Essence

To ascend effort of education quality in Indonesia, generally to ascend quality of mathematics education that still to ascend straight. Because another people believe that mathematics as mother of sciences. For that, need definite success student factor learning. Except that mathematics as discipline knowledge have special specially equal purpose other knowledge that must to see the mathematics essence in student learning. The mathematics essence are:

• Mathematics as pattern: This means student is given freedom and opportunity to do invention activity and attempt. They study finally student can conclude.
• Mathematics as communication: This means that communication can send train of thought self to another people.
• Mathematics as investigation: Student can identify question for investigation, query assumption, negotiate meaning of term with to bring together the proof, make conjunctures, make arguments, and will give logics conclusion based on idea and the relation of them.
• Mathematics as deductive design: This means that truly of concept or conclusions logic consequence for truly proceeding. So that relation of concept or conclusion mathematics is consistent.
• Mathematics as idea design: This means is problem solving process with truly order and logic. So mathematics lesson means learning to rational and logic thingking.
• Mathematics as sign language: This means that mathematics as sign to expression and symbolize a number of means from arguments that will to talk.
• Mathematics as problem solving: Mathematics as problem solving because in mathematics most of student make problem and finalize the problem. For the purpose students is expect can break or does problem mathematics by the way of them self.
  

My comment in Marsigit's blogs about cylinder, cone, and sphere:
"I know this blogs discuss about mathematics for junior high school. But this matter too part of university student. In this blog Dr. Marsigit written learn destination well. Although nothing picture in there, but Dr. Marsigit can giving description with chapter about cylinder, cone, and sphere. Anything else with the example that more than easy to understand and know about cylinder, cone, and sphere. Along with to complete practice can measure how as many as understand student about cylinder, cone, and sphere.
Thank you Dr. Marsigit….. "
