Study Notes

Trigonometry is a branch of mathematics that focuses on the relationships between the sides and angles of triangles and is an essential branch for understanding geometry and geometry-related problems. It is further classified into two sub-branches: Plane Trigonometry and Spherical Trigonometry

Trigonometry is concerned with specific functions of angles and their application to calculations. The six most commonly used trigonometric functions are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc) These functions are used to find the missing or unknown angles or sides of a right triangle using trigonometric functions or identities

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 sine function is given by sin(θ) = r sin(θ), where r is the radius of the circle and θ is the angle in radians

Trigonometry is used in a number of different branches of mathematics and in many different types of problems. For example, it is used in geometry to find the missing sides or angles of triangles, in trigonometry to find the values of trigonometric functions for different angles, and in many different types of problems in the study of functions and their graphs

In trigonometry, angles can be measured in degrees or radians. Some of the most commonly used trigonometric angles for calculations are 0°, 30°, 45°, 60°, and 90°

Trigonometry is an important branch of mathematics that deals with the relationships between the sides and angles of triangles. It is used in a number of different branches of mathematics and in many different types of problems. It is essential for students who wish to pursue Science, Technology, Engineering, and Mathematics (STEM) courses, as it is a prerequisite knowledge for learning Calculus in senior mathematics
