Trigonometry is essential for solving problems involving triangles, circles, and periodic functions. Below are common examples to help you grasp its applications:

🔢 Basic Concepts

  • Sine, Cosine, Tangent:
    In a right-angled triangle, these ratios define relationships between angles and sides.

📌 Common Problems

  1. Finding Missing Sides:
    Use the Pythagorean theorem or trigonometric ratios.
    Example: If sin(θ) = 3/5, find the hypotenuse when the opposite side is 6.
