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 $\displaystyle sin(2\pi x)=0$?

What if you wrote your equation as

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