    Substitute , expand and integrate term-by-term.

    (Note: There is a difference between not being able to do a problem because you're stuck and not being able to do a problem because it involves a lot of spade work and you don't want to get dirty. MHF is not here to save people from getting dirty.

    So do the spade work. Post what you can do and make it clear where you get stuck.)

    i substitute the form cos [z sin x], sin [z sin x], etc. with jacobi-anger expansion, expand it, and i intgrate it term by term. i get the result but in a very long form of the equation.

    i've did it and i'm willing to do the spade of work. help i need is methods to solve this problem but not with jacobi-anger expansion. so if you have any idea i'd really appreciate it. so do you have any idea?
