2. mata kuliah statistik: statistic subjects -> one of the subjects in mathematics wich studied about a numerical datum, a numerical value, such as standard deviation or mean, that characterizes the sample or population from wich it was derived.
based from the informations in http://www.thefreedictionary.com, statistic as a branch of applied mathematics concerned with the collection and interpretation of quantitative data and the use of probability theory to estimate population parameters
from http://www.geocities.com, statistic is defined as following the science that looks into the generic phenomena, formally complex and framed in a variable universe by means of the employment of reduction models of introduction and validation analysis of the results in representative terms. we can verify that the calculation of the mean is a strictly mathematical operation, and in a strict sense, the fault in the example is the interpretation of an arithmetic result.
in the other side, from http://mathnstuff.com explain that a statistic is a one number description of a set of data, or number used as measurements or counts. Mathematicians use the statistic to describe data much as you might use one word to describe a situation or thing or person. it's not a perfect summary, but it's all that might be needed.
3. aplikasi komputer dalam pembelajaran matematika: the applications of computer in mathematics learning.
based from http://www.anrushmath.wordpress.com, computer have a lot of advantages for our life. for instance in education, the applications of computer not only used for administration, but also used as one of the alternative choice for the effective learning. because used computer can built a motivation and also can make student exited to study. used computer for learning make the student easier to understand the subject matter.
4. teorema dasar: elementary theorem
based from the http://thefreedictionary.com, the definitions of theorem is a statement proved on the basis of previously accepted or established statements such as axioms. in formal mathematical logic, the concept of a theorem may be taken to mean a formula that can be derived according to the derivation rules of a fixed formal system. the statements of theory as expressed in a formal language are called its elementary theorem and are said to be true.
for example: the calculus theorem
5. bilangan desimal: the decimal number
based from http://encyclopedia2.thefreedictionary.com, decimal is a fraction that has a denominator of a power of ten, the power depending on or deciding the decimal place. it's indicated by a decimal point to the of numerator, the denominator being omitted. zeros are inserted between the point and the numerator, if necessary, to obtain the correct decimal place. the numbering system used by humans, which is based on 10 digits. In contrast computer use binary numbers because it's easier to design electronic system that can maintain two states rather than 10. decimal notation is the writing of numbers in the base ten.
from the http://www.mathleague.com, the example of the decimal number is 3,762. as with whole numbers, a digit in a decimal number has a value which depends on the place of the digit. the places to the left of the decimal point are ones, tens, hundredths, and so on, just as with whole numbers. in the number 3,762, the 3 is in the ones place, the 7 is in the tenths place, the 6 is in the hundredths place, and the 2 is in the thousandth place
6. bilangan tidak real: unreal number, imaginary number
based from the definition from the http://www.yourdictionary.com, imaginary/unreal number is designating or of the square root of a negative quantity, or of a complex number that is not a real. unreal number is a complex number in the form a+bi where b is not zero, when a is zero, its a pure imaginary number.
from http://www.mathsisfun.com, unreal number is a number that when squared gives a negative result. The unit imaginary numbers (the same as "1" for Real Numbers) is √(-1) (the square root of minus one), and its symbol is i, or j.
7. tidak terhingga/tidak terdefinisi: unlimited
http://www.dictionary.net, unlimited is having no bounds. a problem which is capable of an infinite number of solutions.
http://www.wiredal.wordpress.com, unlimited is having no restrictions or controls, having or seeming to have no boundaries; infinite, without qualification or exception; absolute.
the notation for unlimited is " ~ "
is a collection which it doesn't have member. null set was once a common synonym for empty set, but this usage should be avoided because "null set" is now a technical term in measure theory (http://en.wikipedia.org). the notation for the null set are { }
take from http://www.onlinemathlearning.com, the definition of the null set or the empty is there are some sets that do not contain any element at all. for example: the set of months with 32 days. We call a set with no elements the null or empty set. It is represented by the symbol { } . the other example: {1, 3, 5, 7, 9, ...} ∩ {2, 4, 6, 8, 10, ...} = { }
9. prisma segiempat: rectangular prism or square prism
based from http://www.mathforum.org, the rectangular prism can be thought of as the shape you'd get if you put a rectangle flat on the table in front of you and then lift it straight up and imagine that it leaves a shape behind it as it goes.
10. luas kubus: surface area of cuboid
based from http://www.mathforum.org, the surface area of an objects means how much paper it would take to cover it (or how much paint, if you follow the directions and don't put it on too thick or too thin). cubes are three dimensional, it involves the height, width, and thickness. but if we talking about the surface area, we have to be careful, because although the objects you're measuring has three dimensions, you're just measuring its surface, which like a piece of paper is two-dimensional.
the formula for surface area of cubes is: A= 2wd + 2dh + 2hw. (w=width, d=depth, h=height)
The square cuboid, square box or right square prism (also ambiguously called square prism) is a special case of the cuboid in which at least two faces are squares. The cube is a special case of the square prism in which all faces are squares.
11. pembuktian: proof
based from http://www.thefreedictionary.com, proof is the validation of a proposition by application of specified rules, as of induction or deduction, to assumptions, axioms, and sequentially derived conclusions. in maths, proof is logic a sequence of steps or statements that establishes the truth of a proposition
12. limas segitiga: triangular pyramids
based from http://www.easycalculation.com, the definition of pyramid is a polyhedron with one face as base, a polygon and all the other faces triangles meeting at a common polygon vertex as the apex. so the meaning of triangular pyramid is a geometric solid with a base that is a triangle and all other faces are triangles with a common
13. laboratorium komputer: computer laboratory
a laboratory wich has a computer media in it
14. perhitungan tunggal: single calculation
15. bilangan pecahan: fragment numeral
a fragment numeral is a number which the amount of this less than or more than a whole numeral. for examples: ¼, ¾, ½
16. rumus: formula
based from http://www.thefreedictionary.com, formula is a statements, especially an equations, of a fact, rule, principle, or other logical relation
example: the formula of phytagoras is A²=B²+C²
17. perangkat peragaan: the demonstration equipment
the demonstration equipment is an equipment which used to demonstrate about something.
18. proposal: proposal
based from http://www.ardictionary.com, the definition of proposal that which is proposed, or propounded for consideration or acceptance. proposal is something proposed (such as a plan or assumption)
19. balok: rectangular prism
from http://www.mathsisfun.com, rectangular prism is a solid (3-dimensional) object which has six faces that are rectangles. It is a prism because it has the same cross-section along a length.
its explained in number 9 before.
the rectangular prism based from http://www.mathforum.org, the rectangular prism can be thought of as the shape you'd get if you put a rectangle flat on the table in front of you and then lift it straight up and imagine that it leaves a shape behind it as it goes.
20. kalkulator: calculator or calculating machine
based from http://www.thefreedictionary.com, the meaning of calculator is device for performing numerical computations, it may be mechanical, electromechanical, or electronic. calculator is a machine for performing arithmetic operations and certain mathematical functions automatically
21. sempoa: abacus
frOM http://www.yourdictionary.com, abacus is a frame with beads or balls that can be slid on wires or in slots, for doing or teaching arithmetic
22. trapesium: trapezoid
