Hello,
If you really want to follow the steps you show in your original post, then you can make f a function.
Clear["Global`*"]
f[a_,b_]:=Sin[a x+b]
Manipulate[Plot[f[a,b],{x,0,4 \[Pi]}],{a,0.5,2},{b,0,2 \[Pi]}]

Subject: [mg122795] Question about Manipulate
I tried the following code in Mathematica 8.0
Clear["Global`*"]
f = Sin[a x + b]
Manipulate[Plot[f, {x, 0, 4 \[Pi]}], {a, 0.5, 2}, {b, 0, 2 \[Pi]}]
The Manipulate block is showed, but the Sin function is not plotted.
When I replace f in the third line with its definition,
Clear["Global`*"]
Manipulate[ Plot[Sin[a x + b], {x, 0, 4 \[Pi]}], {a, 0.5, 2}, {b, 0, 2 \[Pi]}]
The Sin function is plotted.
Is this a bug or a limitation in Mathematica?
