  1. Question 1

    Q1. For the equation sin(2x) + sin(4x) + sin(6x) = 0, the general solution is

    • A) nπ/4
    • B) nπ/3
    • C) (2n + 1)π/4
    • D) nπ/2 or (2n + 1)π/4

    Answer: nπ/2 or (2n + 1)π/4

    Explanation: Using sum-to-product identity, the equation simplifies to a form that gives the general solution nπ/2 and (2n + 1)π/4.
