What is Trigonometry

Trigonometry is an area of math who studies the relations that have each of the elements of a right trianglethat is, a triangle with one of its sides measuring 90 degrees or 90º.

Trigonometry already existed more than 3000 years ago, when the Babylonians and Egyptians used the angles of triangles to build pyramids and other complex architectural structures up to modern technology.

The stars from the sky inspired us to go even deeper into trigonometry to discover its “secrets” by creating star maps to calculate routes, prediction of weather and space phenomena, clocks, calendars, etc.

The sine function of trigonometry was already worked on by the Arab astronomers of the 8th century. Two centuries later they had already completed 6 functions and demonstrated the fundamental theorems of trigonometry.

Trigonometry became an independent branch of Mathematics when the current reached Europe and separated it from Astronomy.

In the 17th century, Isaac Newton discovered the series for sin x and other similar series for cos x and tangent (tan or tg)

Basic Trigonometry

The 3 basic functions that must be considered to understand trigonometry are: the sine of x (sinx)he cosine of x (cosx) and the tangent of x (tanx or tgx). In this case we will exemplify the angle as alpha (α):

Trigonometry comes from the composition of the Greek word trigons What does triangle mean and the word meters which means measurement, measurement.
