Homework Help: Funny trig

  1. Mar 28, 2012 #1
    1. The problem statement, all variables and given/known data

    How do I get y'' - yω2 = y'(sinωx + sinhωx) + y(cosωx*ω + coshωx*ω)

    equal to

    y'' - yω2 = sinωx + sinhωx

    I'm baffled.

    2. Relevant equations



    3. The attempt at a solution

    I don't think you can. The most you can recognize is that the term on the right hand side looks like the differentiation of the product of two functions.
