The binary numeral system is a positional number system with base 2. All numbers in this system are written using two symbols 0 and 1. The binary number system has a rich history and is still used in computing. It gave impetus to the development of Cybernetics.

A pyramid is a polyhedron whose base is the polygon and its sides represent triangles having a common vertex. To the right of the pyramid is fairly the same definition, but at the base is a regular polygon. Under the height of the pyramid refers to the segment, which is conducted from the top of the pyramid to the base, and this segment is perpendicular to it. Find the height in a right pyramid is very easy.

A large part of the curriculum of mathematics is the study of functions, in particular, checking for even parity and odd parity. This method is an important part of the process of learning the behavior of a function and plotting its graph.

Often in problems in plane geometry and trigonometry required to find the base of the triangle. For this operation there is even a few methods.

Each section of a scientific or practical knowledge uses its own set of concepts and definitions. They are necessary for us to make a more comfortable understanding and using the various phenomena or actions described with these terms. "Private" applies to such terms used in the description of one of the four elementary mathematical operations.

The mathematical concept of a function clearly shows how one value completely determines the value of the other variable. Usually deals with numeric functions that are put in the corresponding one of the other numbers. A zero of a function, usually called the value of the argument at which the function becomes zero.

Logarithm number b for the base a is defined as a measure of the degree to which it is necessary to build a base a, to obtain the number b. As a rule, modern calculators allow you to calculate logarithms base 10 and e, that is, decimal (log) and natural (ln) logarithms , respectively.

A parallelepiped is a polyhedron consisting of 6 edges, each of which is a rectangle. In order to know its volume, you must use the same formula.

As you know, the perimeter of a plane figure is the length of the bounding lines. To find the perimeter of a polygon is sufficient to add the lengths of its sides. It will have to measure the length of all component segments. If polygon is correct, then the task of finding the perimeter much easier.

Linear system with three unknowns has multiple solutions. Find the solution of the system using the rules of the Kremer via determinants, Gauss method or using the simple method of substitution. The substitution method is a basic for the solution of linear systems of equations of smaller order. It is the successive terms of each equation of the system one unknown variable, substituting it in the equation and simplify the resulting expressions.

Finding a diagonal right prism is often used as an intermediate step for more complex tasks. The General formula is easily derived by consideration of two right triangles.

Magic squares – one of the oldest problems in mathematics. To learn how to solve them, you need to understand the principle. Use the following solution algorithm, which will help you to learn how to deal with this tricky task.

Side of the triangle can be found not only on perimeter and area, but on a given side and corners. For this purpose trigonometric functions - sine and cosine. The problem with their use meet in the school geometry course, as well as in the College course of analytical geometry and linear algebra.

There are two versions of the problem statement: 1) when you need to determine the mass fraction of the element in the substance; 2) when it is necessary to determine the mass fraction of the solute.

The extremes represent the maximum and minimum values of the function and treat its most important characteristics. The extrema are at critical points of the functions. Moreover, the function at the extremum to the minimum and maximum changes its direction accordingly to the sign. According to the definition of the first derivative of the function at the extremum point equals zero or is missing. Thus, the search of extrema of the function consists of two main tasks: finding the derivative for the given function and determine the roots of its equation.

Under the pyramid implies one of the varieties of polyhedra whose base is the polygon and its sides are triangles, which are joined into a single, common vertex. If from the vertex drop a perpendicular to the base of the pyramid, the resulting cut will be called the height of the pyramid. To determine the height of the pyramid very easily.

The base of a parallelepiped is always a parallelogram. To find the area of the base, calculate the area of this parallelogram. As a special case, it can be a rectangle or a square. You can also find the area of the base of the box, knowing its volume and height.

The perimeter of a plane figure is the sum of the lengths of all its sides. But to find the sides of the figure, knowing only the perimeter is not always feasible task. Often, more data are needed.

If you are given two points, then you can safely say that they lie on the same straight, because through any two points you can draw a straight line. But how do you find out, lie all the points on the straightif points three, four, or more? To prove the belonging of points one direct in several ways.

Smaller base of the trapezoid (or a small base) is the least of its parallel sides. The length of this side you can find a variety of ways, using a variety of data. That is the way they are being addressed in this article.

The smallest positive period of a function in trigonometry is denoted by f. It is characterized by the smallest value of a positive number T, that is, the smaller the value of T will not be a periodω of the function.

When solving geometric problems are usually measured some parameters, if known to others. For example, if you specify the area and width of the rectangle, we can find its length. Similar problems often have to solve in practice the measurements or layout of housing, land or purchase building materials.

The apofema in the pyramid is called a line segment, drawn from its top to bottom one of the sides if the cut is perpendicular to the ground. The side faces of such a volume always has a triangular shape. So if you need to calculate the length of apodeme acceptable use of the properties of a polyhedron (pyramid), and polygon (triangle).

A prism is called a polyhedron whose base are equal polygons. The side faces of the given geometries represent the parallelepipeds. They can be perpendicular to the bases, and in this case, the prism is called a straight line. If the faces with the base an angle, the prism is called oblique. The lateral surface area is determined in these cases in different ways.

Prism - a polyhedron with two bases which are equal the polygon and the lateral faces parallelograms. That is, find the area of the base of the prism means finding area of a polygon.

Trigonometric functions are periodic, that is repeated after a certain period. Because of this, it is sufficient to investigate the function on this interval and was found to distribute properties to all other periods.

Free angle, or the angle at the vertex of a polygon composed of two sides, therefore, the task of its construction on paper is reduced to the construction of two adjacent to each other segments. The lengths of these segments can be linked to the size of the angle using the trigonometric functions in a right triangle. This means that you can draw the angle with a protractor do not measure its value, only asking with this line is calculated using trigonometric functions, the lengths of the sides.

Trapezoid is a two-dimensional geometric figure with four vertices and only two parallel sides. If the length of its two non-parallel sides equal, then the trapezoid is called isosceles or isosceles. The border of such a polygon is composed of its sides, denoted by the Greek word for "perimeter". Depending on the input data set to compute the perimeter we need to different formulas.

Parabola – one of the curves of the second order, it is constructed in accordance with a quadratic equation. Most importantly in the construction of this curve is to find the vertex of a parabola. This can be done in several ways.

An isosceles triangle is a convex geometric figure with three vertices and three connecting segments, two of which have the same length. A sine is a trigonometric function that can be used for the numerical expression of the relationship between the ratio of side lengths and angle measures in all triangles, including isosceles.
