What are sine, cosine, and tangent and how do I use them in trigonometry?
Understanding Sine, Cosine, and Tangent in Trigonometry
In South Africa, Grade 11 students delve into the world of trigonometry, where they encounter the concepts of sine, cosine, and tangent. These functions are crucial in calculating the relationships between the angles and sides of triangles.
- Sine (sin): Opposite/Hypotenuse
- Cosine (cos): Adjacent/Hypotenuse
- Tangent (tan): Opposite/Adjacent
By understanding and applying these functions, students can solve various real-world problems involving angles and distances. Trigonometry plays a vital role in fields such as engineering, physics, and architecture. Mastering these functions opens new doors to mathematical applications.
