Homework Help: Superposition of Two Waves

  1. Oct 15, 2011 #1

    I have a question on superposition of two waves and I am pretty new to the topic. I am not contended with my solution and seek your evaluation. Any suggestion, comment is welcome.

    Thanks in advance.

    1. The problem statement, all variables and given/known data

    Consider the superposition of two waves x1 = A1 cos(ω1t) and x2 =
    A2 cos(ω2t + δ). If ω1[itex]\cong[/itex] ω2,
    (a) What is the beat frequency?
    (b) What is the maximum amplitude?
    (c) What is the minimum amplitude?

    2. Relevant equations

    Trigonometric identities for Product-to-sum and sum-to-product.

    3. The attempt at a solution

    Your work is too hard to read. Writing too light.

    Anyway, this is just high school trig, really.
