# How is trigonometry used by architects

## The 11 most important trigonometry uses

There are different Applications of trigonometry in science and in daily life. One of the most notable examples of this is mathematics, as it intervenes in all of its areas.

Its other main uses are shown in navigation, geography, astronomy, architecture and in all fields of engineering.

The use of trigonometry in science and in everyday life because it gives precise measurements.

The measurements are obtained by examining the relationships between the sides of the triangles in terms of angles.

This requires the use of the trigonometric functions sine, cosine, tangent, cotangent, secant and cosecant.

Trigonometry is the branch of mathematics that is necessary for both the geometric study for computation and mathematical analysis.

The use of trigonometry in science and in everyday life dates back to around 4000 BC. C.

According to historical data, the use of trigonometry began in Babylon and Egypt, as its buildings were necessary to make large stones.

### 1- Applications in astronomy

Trigonometry is used in astronomy to calculate the distance from the earth to the sun, the moon, the radius of the earth and also to measure the distance between planets.

To make these measurements, to make use of triangulation, which include, from various points of view, what is desired to be measured and which in each case are to be checked as the corner points of the triangles; from there the distance between one point and another is drawn.

Egyptians set up to measure angles in degrees, minutes and seconds, and in astronomy.

### 2- Applications in architecture

The application of trigonometry in architecture is something that should never be missed. The creation of the plans and their subsequent execution depend on their use.

The creation of a house or building must follow certain parameters. For example: every corner of the walls and pillars should be measured to avoid any misalignment that could eventually cause the building to collapse.

A clear example of the use of trigonometry in architecture in the Egyptian pyramids and constructions seen from the civilizations that inhabited America before the arrival of the Spaniard.

It is through the application of trigonometry that these buildings are almost intact over time.

Trigonometry was used in navigation for many years and it created what is now known as a sextant, an instrument that could measure the distance from the sun or triangulation to the stars.

The sextant was used as follows: it should determine the angular height of the sun (or stars or a star that can serve as a reference point) above the horizon.

Later she was able to perform mathematical calculations to determine the point at which the observer is, that is, the person who is using the sextant.

Knowing two points on a coast or an island, sextant could also be used to measure the distance that boats were coast.

The sextant was responsible for guiding the captains of the ships. Currently the sextant has been replaced by satellite systems. These also make use of the use of trigonometry.

### 4- Applications in geography

In geography, trigonometry is used to calculate distances on a map; That said, it uses parallels and meridians to calculate length.

### 5- Applications in video games

Trigonometry is used for video game programming. Hence, anything presented on the screen requires trigonometry.

### 6- Applications in construction

An example of the use of trigonometry in civil engineering is seen through the construction of bridges, roads, buildings and the land rising stroke, among other things.

### 7- Applications in mechanical engineering

Trigonometry is used in mechanical engineering for the construction and measurement of parts in series. It is also used to project forces.

### 8- Applications in electrical engineering

Trigonometry is used in electronics to identify the behavior of rows and signals.

Trigonometry helps establish connections and locate positions that favor the process of distributing electricity.

### 9- applications in the pool

Trigonometry is used in this board game. Based on the collision between the balls, it makes certain angles to go in a certain direction.

These angles are used by each player to determine what their next move will be.

### 10- Applications in Physics

Trigonometry is used to measure the trajectory of an object. If, for example, a soccer game you want to make an air passage it is necessary to find an angle and also have defined the point where it is directed.

Taking all these points into account, the trajectory of the ball can be calculated. This can also be used to measure the trajectory of a projectile, a missile, among other things.

### 11- Applications in medicine

Trigonometry is used in medicine to read electrocardiograms, a test that graphically records the electrical activity of the heart as a function of time.

In these studies, functions of the breast and the cosine appear. Depending on how they appear, they are given a letter that gives meaning to the wave. So doctors can read it and diagnose it in time.
