The strange thing is that the Prime already does this when solving trigonometric equations: try solving \(\sin(x)=\frac12\), with "Principal" unticked in the CAS settings. So the mechanism is there, but for some reason it isn't applied to inequalities.

After unticking Pricipal in CAS settings and trying to solve \(\sin(x)=\frac12\), I have this result:

(12*n_24*π+π)/6, (12*n_24*π+5*π)/6, what does mean 12*n_24*π ?

Thanks

n_24 is an arbitrary integer. If you run the command again you should get n_25 in the answer, and so on. This is better than using n or c or k, as these are common variable names which might already be in use elsewhere.
