30+ Trigonometry Free Books

Trigonometry is a branch of mathematics that is the study of trigonometric ratios, such as sine, cosine, tangent, cotangent, secant, and cosecant. Etymologically, trigonometry is known as the “measurement of triangles”, but its applications transcend the mathematical and geometric plane. The field of astronomy uses trigonometric techniques to measure distances between stars, geographical points, and satellite navigation systems. In the mathematical field, trigonometry has contributed multiple functions that have transcended its main objective to become independently studied elements. It is also a concept applied in plane geometry in solutions of equations. In everyday life, trigonometry allows us to calculate distances, measure angles, and so on. If you want to explore more about trigonometric tools and how to apply them to your field of study, take a look at the trigonometry books we have selected for you.

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.
