I have this plot:
Plot[1 - 3 (x/l)^2 + 2 (x/l)^3 /. l -> 1, {x, 0, 1},
AxesLabel -> {x, Superscript[\[Psi] , (1)] [x]},
PlotStyle -> AbsoluteThickness[4],
AxesStyle -> AbsoluteThickness[1.5], BaseStyle -> {FontSize -> 14}]
But the rounded parentheses are hidden (and I need them :-) )! Can I force mathematica to show them in some way?
