Hi Alexandre
Here are some ideas:
Plot[ Sin[x], {x, 0, 6 \[Pi]} ]
Plot[ Sin[x], {x, 0, 6 \[Pi]}, PlotRange -> {-0.5, +0.5} ]
sinTruncated1[ x_ ] := If[ -0.5 <= Sin[x] <= +0.5, Sin[x]]
Plot[ sinTruncated1[x], {x, 0, 6 \[Pi]}, PlotRange -> {-1, 1} ]
sinTruncated2[ x_ ] :=
Which[ -0.5 <= Sin[x] <= +0.5, Sin[x], Sin[x] < -0.5, -0.5,
Sin[x] > +0.5, +0.5]
Plot[ sinTruncated2[x], {x, 0, 6 \[Pi]}, PlotRange -> {-1, 1} ]
You will get many more from other Group members.
Cheers
Barrie
