These are the definitions, examples, and explanations of the terms in the rom I made by Heni Ayu Pertiwi, which I write in the English language as a result of a dictionary, thesaurus, learn the English language books, internet download, opened the marsigit’s blog, and also follow Mr.marsigit’s lesson in the class.

1. Akar kuadrat: Square root.

· Square root: A divisor of a quantity that when squared gives the quantity.

For example, the square roots of 25 are 5 and -5 because 5 × 5 = 25 and (-5) × (-5) = 25.

· Square root (Noun): A number that when multiplied by itself gives a given number. The square roots of 4 are 2 and -2 .

2. Nilai mutlak: Absolute value.

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

For example, the absolute value of -4 (written -4) is 4. Also called numerical value.

• The modulus of a complex number, equal to the square root of the sum of the squares of the real and imaginary parts of the number.

3.Diintegralkan: Integraled

· A number computed by a limiting process in which the domain of a function, often an interval or planar region, is divided into arbitrarily small units, the value of the function at a point in each unit is multiplied by the linear or areal measurement of that unit, and all such products are summed.

• A definite integral.
• An indefinite integral.

the sum of a large number of minute quantities, summed either between stated limits ([definite integral]) or in the absence of limits ([indefinite integral])

4. Hasil bagi: quotient

• The number obtained by dividing one quantity by another.

For example, In 45 ÷ 3 = 15, 15 is the quotient.

• The result of the division of one number or quantity by another [Latin quotiens how often]
• The number that results when one number is divided by another. If 6 is divided by 3, the quotient can be represented as 2, or as 6 ÷ 3, or as the fraction ⁶/₃.

5. Kongruen : Congruence.

As an abstract term, congruence means similarity between objects. Congruence, as opposed to equivalence or approximation, is a relation which implies a kind of equivalence, though not complete equivalence.

In mathematics, congruence is formally represented by a tilde over an equal sign , whereas approximation is jointed by the double-tilde . In both cases, the single tilde (~) may sometimes be used as a substitute (which may cause confusion due to its usage in logic and computer programming languages for representing negation). Congruence modulo n is usually denoted "≡" (see congruence relation for an example).

• In arithmetic, algebra and encryption, congruence refers to a congruence relation.
• In euclidean geometry, congruence refers to the equivalence of shapes. See congruence (geometry).
• In the theory of smooth manifolds, especially in the context of general relativity, congruence refers to the integral curves defined by a vector field.
• In psychology and NLP, congruence could be defined as rapport within oneself, or internal and external consistency, perceived by others as sincerity or certainty.
• An alternative definition of congruence in the work of Virginia Satir, one of the sources of NLP, is the balance between self, other and context.
• In cladistics, congruence is a test of homology, or shared, derived character states, in which the distributions of supposed homologies among taxa are compared for consistency.
• horizontal and vertical congruence, two related principles of grouping

6. Sejajar: Parallel.

Parallel is a term in geometry and in everyday life that refers to a property in Euclidean space of two or more lines or planes, or a combination of these. The existence and properties of parallel lines are the basis of Euclid's parallel postulate.

Euclidean Parallelism

As shown by the tick marks, lines a and b are parallel. We can prove this because the transversal t produces congruent angles.

Given straight lines l and m, the following descriptions of line m equivalently define it as parallel to line l in Euclidean space:

1. Every point on line m is located exactly the same minimum distance from line l ('equidistant lines', not including the degenerate case where m = l).
2. Line m is on the same plane as line l but does not intersect l (even assuming that lines extend to infinity in either direction).
3. Lines m and l are both intersected by a third straight line (a transversal) in the same plane, and the corresponding angles of intersection with the transversal are equal.

In other words, parallel lines must be located in the same plane, and parallel planes must be located in the same three-dimensional space. A parallel combination of a line and a plane may be located in the same three-dimensional space. Lines parallel to each other have the same gradient. Compare to perpendicular.

7. Kelipatan : multiple.

1. Having, relating to, or consisting of more than one individual, element, part, or other component; manifold.
2. A number that may be divided by another number with no remainder.For example, 4, 6, and 12 are multiples of 2.
3. the product of a quantity by an integer; "36 is a multiple of 9"
4. mathematical product, product - a quantity obtained by multiplication; "the product of 2 and 3 is 6"

8. Koordinat:coordinate

1. One that is equal in importance, rank, or degree.
2. Mathematics Any of a set of two or more numbers used to determine the position of a point, line, curve, or plane in a space of a given dimension with respect to a system of lines or other fixed references.

Noun1.coordinate - a number that identifies a position relative to an axis

co-ordinate

a) Cartesian coordinate - one of the coordinates in a system of coordinates that locates a point on a plane or in space by its distance from two lines or three planes respectively; the two lines or the intersections of the three planes are the coordinate axes

b) polar coordinate - either of two values that locate a point on a plane by its distance from a fixed pole and its angle from a fixed line passing through the pole

number - a concept of quantity involving zero and units; "every number has a unique position in the sequence"

9. Logika dan Himpunan : logic and collection

Logic and collection: The study of the principles of reasoning, especially of the structure of propositions as distinguished from their content and of method and validity in deductive reasoning.

10. Tegak lurus : Perpendicular.

1. Mathematics, Intersecting at or forming right angles.
2. Being at right angles to the horizontal; vertical. See Synonyms at vertical.

1. at right angles to a given line or surface

2. upright; vertical

Noun1.perpendicular - a straight line at right angles to another line

straight line - a line traced by a point traveling in a constant direction; a line of zero curvature; "the shortest distance between two points is a straight lin

11. Bilangan kuadrat : Square number

Square number : a natural number that can be shown as a result multiple two same number.

For example, 9 is the square number of 3.

12. Luas : Area, wide

Area: size of a surface

For example, a wide rectangle is 16 m

13. Lebih dari sama dengan : more than equal

More than equal: use to indicate a number greater or equal.

For example, x more than equal from y.

14. kurang dari : less than…

Less than : Used to indicate a number is smaller than the other.

For example, x less than 3.denoted by x < y

15. Titik belok : point convolution

Point where changes occur in the concavity of a sunken kurva up to become a concave bottom, or vice versa.For example, point convolution function f (x) = X3 +1 at the point (0, 1).

16. Nilai Ekstrim : Ekstrim value

Ekstrim value : used to determine the value of the maximum curve.

17. Pemisalan : assumption, premise, taking an example

assumption - a statement that is assumed to be true and from which a conclusion can be drawn; "on the assumption that he has been injured we can infer that he will not to play"

18. Saling bersinggungan : mutual touch,jog

19. Saling berpotongan : Have the look of

when two lines meet at one point.For example, lines A and B each have the look in C.

20. Bilangan Ganjil dan Genap : odd number & even number

• Odd number : A natural number not divisible by 2.

For example, 1,3,5,7 ... including the odd number

• Even number: A natural number divisible by 2.

Example the even number is 2,4,6,8….
