# Solve trigonometric equation

How do I solve simple trigonometric equation 2*cot(2x)=0?

I tried solve, but it gives me one solution, I need solution with n.

Thank you.

With
`solve(2*cot(x)==0, x, to_poly_solve = 'force')`

you will get all solutions, where $\pi z_{xx}$ should be interpreted as a multiple integer of $\pi$.
