2024-09-04 21:56:57 +0200 marked best answer Solving this differential equation

I'm trying to solve this de but get an error which I don't understand.

x = var('x')
y = function('y')(x)
de = diff(y, x) == tan(y) * (y^3 - y)
desolve(de, y)
TypeError: ECL says: changevar: fourth argument must be an atom; found: 'y(_SAGE_VAR_x)

I would also like to plot a maximum solution \phi(0) = 0.5.

Thank you

I would like to have the axes displayed with arrow tips at the end. I have seen this question asked before but since that was some time ago I wondered if there is a simple way to do it now that doesn't involve plotting them manually. I appreciate the help.
