WebSine, Cosine and Tangent. Three Functions, but same idea. Right Triangle. Sine, Cosine and Tangent are the main functions used in Trigonometry and are based on a Right-Angled Triangle.. Before getting stuck into the functions, it helps to … WebSep 15, 2024 · Example 6.6. Solve the equation cos 3θ = 1 2. Solution: The idea here is to solve for 3θ first, using the most general solution, and then divide that solution by 3. So since cos − 11 2 = π 3, there are two possible solutions for 3θ: 3θ = π 3 in QI and its reflection − 3θ = − π 3 around the x -axis in QIV.
