Basics of Trigonometry Functions and Identities

Trigonometry is a branch of mathematics that focuses on relationships between the sides and angles of triangles and is concerned with specific functions of angles and their application to calculations The six important trigonometric functions, ratios, and identities are:

Sine (sin)
Cosine (cos)
Tangent (tan)
Cosine (cot)
Cosine (sec)
Cosine (csc)

Trigonometry is further classified into two sub-branches:

Plane Trigonometry
Spherical Trigonometry

Trigonometry helps to find the missing or unknown angles or sides of a right triangle using the trigonometric functions or trigonometric identities Some of the most commonly used trigonometric angles for calculations are 0°, 30°, 45°, 60°, and 90°

Trigonometry is used in many different branches of mathematics, such as geometry, algebra, and Calculus, as it is a prerequisite knowledge for learning Calculus in senior mathematics and is essential for students who wish to pursue Science, Technology, Engineering, and Mathematics (STEM) courses

In trigonometry, angles can be measured in degrees or radians The unit circle is a circle with a radius of 1, and it is used to find the values of trigonometric functions for different angles The Pythagorean identity is a trigonometric identity that relates the sine, cosine, and tangent functions of an angle
