1) If I type sin(x|)=0 and press Solve, the software evaluates to Sin(x) [solves nothing]
2) If I put the result in a variable, it evaluates numeral answers, so a=Solve(sin(x)=0) [0, 3.1315, 6.2832]
3) But I want the algebraic form; when a just show the variable a, it evaluates to: [0, pi, 2*pi], which is much nicer and is what a expected in item 1.
