s of tangent? A: Yes, using the identity cos 2x = (1-tan²x)/(1+tan²x). 5. Q: Why are there three forms of the cos 2x formula? A: The three forms provide flexibility depending on the context of the problem. Sometimes, having the formula expressed purely in terms of sine or cosine is more advant

Cos2x

alue of cos(120°). We know that 120° = 2 60°. Using the formula cos2x = 2cos²x - 1, we have: cos(120°) = cos(2 60°) = 2cos²(60°) - 1 = 2(1/2)² - 1 = 2(1/4) - 1 = -1/2 Example 2: Simplify the expression 2cos²x - 1 + sin²x. Recognizing the term 2cos²
