This course introduces Valley Technical Training Institute trainees to the fundamental concepts of trigonometry and their practical applications. Students begin by understanding the relationship between angles and sides in right-angled triangles and learn how to use the basic trigonometric ratios—sine, cosine, and tangent—to solve problems involving unknown sides and angles.
The course then explores angle measurement in degrees and radians and introduces the unit circle as a tool for understanding trigonometric functions and their values at standard angles. Students develop skills in converting between degrees and radians and interpreting coordinates on the unit circle.
Building on these foundations, students learn basic trigonometric identities and equations, including the Pythagorean identity and reciprocal relationships. They practice simplifying trigonometric expressions and solving simple trigonometric equations.
Finally, the course emphasizes real-world applications of trigonometry, including determining heights, distances, and angles of elevation and depression. Through practical examples and problem-solving activities, students gain confidence in applying trigonometric concepts to everyday situations and further mathematical studies.
