And why so and not otherwise, what does it depend? Some adverbs and prepositions just need to remember, and in some cases you need to first understand, whether it is adverb or a noun with a preposition, this will depend on the writing. - How to multiply the matrix
Matrix multiplication requires a certain condition: the number of columns of the first matrix multiplier must be equal to the number of rows of the second. In addition, this operation is not commutative, that is, the result depends on the order of the factors. - How to find a leg and the hypotenuse
The leg is one of the sides of a right triangle, which is adjacent to the right angle.The hypotenuse is the side of a right triangle opposite the right angle. There are several ways to find their size. - How to solve equation third degree
Equations of the third degree is also called cubic equations. This equation, in which the highest degree when variable x is a cube (3). - How to find the bases of the trapezoid
The bases of the trapezoid can be found in several ways, depending on the specified parameters. When famous square, the height and the side of the isosceles trapezoids of the sequence of calculations is reduced to the computation of the sides of an isosceles triangle. And to use the properties of isosceles trapezoids. - How to make AC DC
In human life, interested in electronics, often face the task to convert AC to DC. In General, a relatively easy task for the experienced in this field person. But what if you're just starting out in electronics? There are a number of devices that will help us in this - How to translate from English to Russian

A-line is a flat foursquare, of which two opposite sides are parallel. They are called bases of the trapezoidand the other two sides - the sides of the trapezoid. - How to find common denominator
The decision of mathematical tasks with fractions has many ways. One of the simplest and most common operations - addition/subtraction of fractions. If the denominator of both fractions are the same, just folded/subtract the values in the numerator, but if the numbers in the denominators are different, come to the aid of finding the lowest common denominator. - How to find the percentage of the interest
The mathematical definition of the cent, as the hundredth part of the whole from a given number is a manageable problem. However, in life we often find solutions in unusual situations. For example, when the source data is not available, the number and the percentage of the number. For this task it is required to determine the percentage of the percentage. - How to make a Newtonian liquid
A Newtonian fluid is any fluid, which is in accordance with the law of viscous friction Newton. According to this law, the liquid will continue to have flowing properties, regardless of what forces act on it. To do a Newtonian fluid is incredibly simple. - How to break words into syllables
A syllable is a combination of letters in a word that is pronounced with one push of exhaled air. In the study of the Russian language is often necessary to break words into syllables. - How to find the side of a triangle if two sides are known
The solution of the problem developed by the ancient mathematician Pythagoras. All of the plurality of triangles select rectangular. In one of the angles is equal to 90 degrees. Sides that are adjacent to this angle are called the legs. And a third side connecting the other two sides is called the hypotenuse. Let one of the legs is equal to 15 centimeters, and the second was 9 inches. By the Pythagorean theorem we find the length of the hypotenuse. - How to round a number to the hundredths
The task of rounding to the hundredths sometimes appears in programmers. This happens in two cases. First, the language used may not be the corresponding rounding function. Secondly, an inexperienced programmer may not be aware of the subtleties of language. In either case, rescued a 4-step rounding algorithm. - How to translate in decimal system
In machine arithmetic used different systems of notation. Basically, computing is based on binary numbers. In everyday life we are accustomed to using the decimal system of notation. Let's see how to represent decimal numbers represented in other systems of notation. - How to transfer numbers in binary system
In addition to the usual decimal system of notation, there are other systems. The most common ones are: binary, octal, hexadecimal. These systems are mainly used in computing. For converting numbers from one base to another there are simple operations. Consider how to translate numbers into the binary system of notation from other systems. - How to convert a number from decimal system
Are used in computing various systems of notation: binary, octal, hexadecimal. Not always convenient to operate with such numbers, because it is in use accustomed to use a decimal system. So try to figure out how to translate a number from a decimal system of notation to the other. - How to write "for"
The phrase "in the course of"perhaps one of the most difficult in the Russian language. Writing it depends on what part of speech is the word "for". Learn simple rules explaining how to write "in for"and you will be free from spelling mistakes in this life. While studying the rules of main thing is not to memorize but to understand. - How to find the sides if the perimeter is known
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. - How to convert degrees to minutes
In minutes and seconds, as a rule, measured by geographical or astronomical coordinates. These units are rarely used in mathematics, physics, and applications in solving various problems both theoretical and applied nature. Here more application as the unit of measurement of plane angles have degrees, whole or fractional. How to convert minutes and seconds to degrees we now find out. - How to write "nevertheless"
The phrase "none the less" depending on the context, may be separated with commas or used without them. In the first case, the phrase "none the less" must have expressed the importance of introductory words. - How to prepare for state
