    Q1. What is the value of sin(3x) in terms of sin(x)?

    • A) 3 sin(x) - 4 sin³(x)
    • B) 3 sin(x) + 4 sin³(x)
    • C) 4 sin³(x) - 3 sin(x)
    • D) 4 sin(x) - 3 sin³(x)

    Answer: 3 sin(x) - 4 sin³(x)

    Explanation: Using the triple angle formula, sin(3x) = 3 sin(x) - 4 sin³(x), derived from sum and difference identities.
