Section outline

  • n this week, we will study two main topics that form the core of trigonometry.

    You will learn about the trigonometric ratios — sine (sin), cosine (cos), and tangent (tan) — and understand how they relate angles to the sides of a right-angled triangle. You will also be introduced to basic trigonometric identities that help simplify and connect these ratios.

    By the end of this week, you will be able to identify the correct ratio, use simple identities, and confidently move on to solving trigonometric problems.
