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.

It doesn't work for 2*cot(2x). More precisely, solve(2*cot(2*x)==0, x, to_poly_solve='force') returns empty list.
Pay attention to argument of cotangent: it is 2x: see here See equation solver for correct answer.
Ok! Sorry, I don't know why does it return the empy list. Of course, a change of variables var('x, y') and solve([2*cot(y)==0, y==2*x], x, y, to_poly_solve = 'force') will do the job, but it's awkward..
I agree...
