Consider the following code:
Manipulate[
Quiet[Plot[
Piecewise[{{Subscript[V, 0]*a,
x < (a/2)}, {Subscript[V,
0]*((a/2) + (2*Abs[x - ((3*a)/4)])), (a/2) <= x <=
a}}], {x, -a, a}]], {a, 0, 5}, {Subscript[V, 0], 0, 5}]
When I evaluate this it does'nt suppress the errors, does anyone have a solution to this?
