 eliminated

eliminated in linear and multilinear algebra, a process for finding the solutions of a system of simultaneous linear equations by first solving one of the equations for one variable (in terms of all the others) and then substituting this expression into the remaining equations. The result is a new system in which the number of equations and variables is one less than in the original system. The same procedure is applied to another variable and the process of reduction continued until there remains one equation, in which the only unknown quantity is the last variable. Solving this equation makes it possible to “back substitute” this value in an earlier equation that contains this variable and one other unknown in order to solve for another variable. This process is continued until all the original variables have been evaluated.

integral
In calculus, an antiderivative, primitive or indefinite integral[1] of a function f is a function F whose derivative is equal to f, i.e., F ′ = f. The process of solving for antiderivatives is antidifferentiation (or indefinite integration). Antiderivatives are related to definite integrals through the fundamental theorem of calculus: the definite integral of a function over an interval is equal to the difference between the values of an antiderivative evaluated at the endpoints of the interval.
The function F(x) = x3/3 is an antiderivative of f(x) = x2. As the derivative of a constant is zero, x2 will have an infinite number of antiderivatives; such as (x3/3) + 0, (x3 / 3) + 7, (x3 / 3) − 42, etc. Thus, the entire antiderivative family of x2 can be obtained by changing the value of C in F(x) = (x3 / 3) + C; where C is an arbitrary constant known as the constant of integration. Essentially, the graphs of antiderivatives of a given function are vertical translations of each other; each graph's location depending upon the value of C.

3 dimensional

Start with a point, drag it to get a line. Drag a line to get a square. Drag a square to get a cube. Any small translation of a cube has non-trivial overlap with the cube before translation, thus the process stops. This is why space is said to be 3-dimensional.

A straight angle

A straight angle changes the direction to point the opposite way.

An obtuse angle
An obtuse angle is one which is more than 90° but less than 180°

An acute angle

An acute angle is one which is less than 90°

Radian

A Radian is: the angle made by taking the radius and wrapping it along the edge of the circle.

A plane is a flat surface with no thickness. Our world has three dimensions, but there are only two dimensions on a plane. Examples: ength and height, or x and y.

The study system

The study system is a strategy to help you successfully pass the exams in your classes.

arithmetics

is the oldest and most elementary branch of mathematics, used by almost everyone, for tasks ranging from simple day-to-day counting to advanced science and business calculations. In common usage, the word refers to a branch of (or the forerunner of) mathematics which records elementary properties of certain operations on numbers

permutation

In several fields of mathematics the term permutation is used with different but closely related meanings. They all relate to the notion of mapping the elements of a set to other elements of the same set, i.e., exchanging (or "permuting") elements of a set.

triangle

A triangle is one of the basic shapes of geometry: a polygon with three corners or vertices and three sides or edges which are line segments. A triangle with vertices A, B, and C is denoted ABC.

square

A four-sided polygon with all sides the same length and all angles = 90 degrees

rectangle

a rectangle is a closed planar quadrilateral having four right angles.
The shape is like a square, but the sides are not necessarily all equal in length.

cube root

 a cube root of a number, denoted or x1/3, is a number a such that a3 = x. All real numbers have exactly one real cube root and a pair of complex conjugate roots, and all nonzero complex numbers have three distinct complex cube roots. For example, the real cube root of 8 is 2, because 23 = 8.

absolute value

absolute value (or modulus) of a real number is its numerical value without regard to its sign. So, for example, 3 is the absolute value of both 3 and −3.

The absolute value of a number a is denoted by | a | .
