Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles. It may seem like an abstract concept, but trigonometry is actually quite useful in real-life applications. Let's dive into the basics!

Unit Circle: One of the fundamental tools in trigonometry is the unit circle. This is a circle with a radius of 1, centered at the origin of a coordinate plane. It helps us visualize angles and their trigonometric functions.

Angle Measurements: In trigonometry, angles are typically measured in degrees or radians. Degrees are most commonly used, where a full circle is divided into 360 equal parts. On the other hand, radians are used in more advanced mathematical concepts, where a full circle is divided into 2π (approximately 6.28) parts.

Trigonometric Functions: Trigonometric functions, also known as circular functions, are mathematical functions that relate angles to the ratios of the sides of a right triangle. The three main trigonometric functions are sine (sin), cosine (cos), and tangent (tan). These functions provide valuable information about the relationship between angles and sides of triangles.

Understanding the basics of trigonometry sets the foundation for further exploration of more complex concepts and applications. Stay tuned for our next post where we delve into the details of the sine function!
