    Q1. What is the value of sin(2x) in terms of sin(x) and cos(x)?

    • A) 2 sin(x) cos(x)
    • B) sin(x) + cos(x)
    • C) sin(x) - cos(x)
    • D) sin(x) cos(x)

    Answer: 2 sin(x) cos(x)

    Explanation: Using the double angle formula, sin(2x) = 2 sin(x) cos(x), derived from sum and difference identities.
