There are few uses for trigonometry is schools just as there are few uses for languages or history or geography or, in fact, most subjects. There are three main objectives in teaching most subjects at school:
builders
The uses of Sin, Cos etc. in Maths is in relation to Trigonometry. Trigonometry is the study of the relationship between angles and lengths of triangles.
libraries have trig books.
Trigonometry is the study of plane and spherical triangles. Plane trigonometry deals with 2 Dimensional triangles like the ones you would draw on a piece of paper. But, spherical trigonometry deals with circles and 3 Dimensional triangles. Plane trigonometry uses different numbers and equations than spherical trigonometry. There's plane trigonometry, where you work with triangles on a flat surface, then there's spherical trigonometry, where you work with triangles on a sphere.
algebra, geometry, trigonometry, and calculus all use the alphabet.
trigonometry is very imr

Not everyone but trigonometry is needed in the field of construction under certain circumstances
Trigonometry helps you to easily read the rate of heart beats of a person and their blood pressure level as well.

1) Surveying; 2} Architecture; 3)
The ancient rules of trigonometry are still used today in navigation, aviation, architecture, astronomy, building, engineering, education ..... etc
Precalculus is supposed to be a stringent and comprehensive review of both algebra and trigonometry. This is in preparation for calculus which uses both algebra and trig extensively.
algebra, geometry, trigonometry, and calculus all use the alphabet.
There are an enormous number of uses of trigonometry and trigonometric functions. For instance, the technique of triangulation is used in astronomy to measure the distance to nearby stars, in geography to measure distances between landmarks, and in satellite navigation systems.
