# 15+ Trigonometry Books for Free! [PDF]

To further expand the topics of mathematical sciences, we have developed the collection of trigonometry books in PDF format. Created especially for those who wish to master the area or simply study for pleasure.

Mathematics is fundamental for basic education and also for a wide variety of university professions. This makes many people interested in studying it, so we know that our collection of trigonometry PDF books will serve as a foundation for them.

The first glimpses of trigonometry date back to Ancient Egypt and Babylon. In astronomy, the motions of the planets and eclipses were studied and recorded. A rudimentary way of using trigonometry can be seen in the construction of the pyramids.

Trigonometry is understood as the branch of mathematics that deals with the measurement of triangles, i.e. trigonometric ratios such as: sine (calculation of the ratio between the opposite side and the hypotenuse), cosine (calculation of the ratio between the adjacent side and the hypotenuse), tangent (calculation of the ratio between both sides), secant (reciprocal ratio of the sine) and cosecant (reciprocal ratio of the cosine).

The trigonometric ratios of any angle are also studied, which are part of the study of what is known as unit circle.

There are two types of trigonometry: spherical trigonometry, which deals with the study of spherical triangles, and plane trigonometry, which obviously refers to the study and analysis of plane triangles.

Moreover, trigonometry has a wide range of applications in the sciences, such as, for example, in the measurement of distances between celestial bodies or in satellite navigation systems.
