The term “trigonometry” means a branch of mathematics that deals with the connection between angles and sides of a triangle. Trigonometry, like many other areas in mathematics, is a study that extends beyond mathematics. Current telecommunications rely on a thorough knowledge and use of signal analysis, which is represented by trigonometric functions.

Right triangle problems may be solved with our trigonometry calculator. Trigonometry can be learned with the help of our calculator, now calculating the tangent, cosine, or sin of an angle will no longer be difficult for you. Simply enter the degree value of the angle of a triangle in our calculator and click the "tan"  "cos," or "sin," button in our calculator.

All you have to do is complete the right triangle with variables to our trigonometry calculator to get the missing sides or angles of your right triangle. It's also a sure bet that we've got the right tool for you when it comes to right-angle triangle calculations. For more information about trigonometry and how you may use our trigonometric calculator, please continue reading below.

## Definition of trigonometry

Trigonometry is a topic in mathematics that deals with angles. The name is derived from the Greek word trignon meaning("triangle") and metron meaning ("measure"). The term "trigonometry," is mainly concerned with triangles and their angles; specifically, the definition and application of ratios and relationships of triangle sides and their angles. Right triangles in particular, and other forms of triangles you can think of, are the major focus of this program.

Trigonometry serves a variety of purposes in our daily lives. For example, the development of trigonometry was driven by the necessity to calculate distances and angles in professions like mapmaking and astronomy.

When an airplane is landing or taking off, the direction, slope trigonometry, and speed are all used to determine an airplane's route. When trigonometry is used, pilots can determine the ideal landing and takeoff angles and speeds even when there is a strong wind.

Trigonometry studies the connection between a triangle's angles and its sides. You may also discover the distances of other celestial bodies and stars using trigonometry. Trigonometry is also commonly utilized in GPS navigation systems, physics, and architecture. Trigonometry works by comparing two triangles with the same angles. The length of each side may vary, but the side ratios remain constant.

## The use of tan, sin, and cosine

What do the term “tan, sin, and cosine” mean, and how can we benefit from them? It is important to understand trigonometric functions for some reasons. Below are some of the reasons why you should be familiar with the trigonometric functions.

• Using trigonometric functions, we can design geometric objects and produce smooth motions or animations.
• Having a solid understanding of trigonometry functions may be useful in a variety of fields, including but not limited to programming. Take some time to practice if you'd want to become better at it. With a little research, you may uncover solutions to real-world situations with their corresponding calculations.
• Trigonometry is used by game developers, scientists, architects, draftsmen, engineers, and pilots. Mathematicians also use trigonometry in a broad variety of professions, including engineering, architecture, and medicine.
• Students of various ages may benefit from online trigonometry courses. They may increase their overall mathematical abilities and mastery of trigonometry through a dedicated study online. Students who study trigonometry online are better prepared to deal with the difficulties of the subject and have a comprehensive understanding of its meanings.

## The six trigonometric functions

In trigonometry, it is common to apply the six different functions of an angle. The following includes a list of the six trigonometric functions:

• cosine (cos),
• sine (sin),
• cosecant (csc),
• tangent (tan),
• cotangent (cot), and
• secant (sec).

Figures in geometry may be solved using trigonometric functions to find unknown angles and lengths. Look at the illustration below,

sin θ=x/y also known as (opposite side)/( hypotenuse)

cos θ=x/r also known as (adjacent side)/( hypotenuse)

tan θ=y/x also known as (opposite side)/( adjacent side)

There are three reciprocal functions for each of these functions.

csc θ=  r/y(reciprocal of sin θ)

sec θ= r/x (reciprocal of cosθ)

cot θ=x/y (reciprocal of tanθ)

Assume that the perpendicular length is y and that the base length is x. The radius of the unit circle is the same as hypotenuse length, which is 1. As a result, the trigonometric ratios may be written as

tan θ=y/x

sin θ= y/1=y

cos θ=x/1=x

## Buildings height calculation using trigonometry

If a building’s angle of elevation is 350 to the top and 90ft from the ground, determine the building's height. Let’s use the formulas above to find the height of the building.

• The distance between the building's base and the ground is 90 feet.
• 350 is the elevation angle from the ground level up to the top.

Let us calculate the height using the tan formula above, so,

35° (tan) =h/90

h= 90 × 35° (tan)

h= 90 × 0.7002

h= 63.018 m.

So, 63.018m is the height of the building.

The trigonometry formulas above may assist students in becoming familiar with various formulas, which can be useful in quickly solving trigonometric problems. Trigonometry tasks are diverse, and mastering the equations above can assist you in tackling them more effectively. To answer the issue, you may need to apply many formulas, so study and practice each one so you know when to use it.
