    Need some hints for solving this trigonometry equation

    Hi everyone,

    I'm really struggling with this equation, I can't figure out what form is this?Can anyone give me hint where to start?
    5*sin( 10*pi*x ) + 3*sin( 3*pi*x ) = 0

    Thanks,

    Hi,

    for which x does sin(2\pi x)=0?

    What if you wrote your equation as

    5sin(5\cdot 2\pi x) + 3sin(\frac{3}{2}\cdot 2\pi x)=0?
