Welcome to an exciting journey into the world of trigonometric functions and their vital applications in engineering. In this blog post, we will cover the fundamentals of trigonometry, focusing specifically on the trigonometric functions of general angles. Whether you are a student preparing for the board exam or a seasoned engineer, this lecture will provide you with a solid understanding of trigonometric concepts and their practical significance in various engineering disciplines.

Trigonometric functions such as sine, cosine, and tangent are indispensable tools in engineering. They enable engineers to solve complex problems involving angles and distances with ease and precision. In this lecture, we will revisit the definitions of these functions and their relationships within the unit circle, providing you with a thorough understanding of the topic. From there, we will explore how trigonometric functions can be extended to generalize angles beyond the standard unit circle, allowing engineers to work with angles of any magnitude confidently.
