I need help in plotting two graphs together and doing some sort of manipulation. I have a sequence:
A=ListPlot[List, PlotRange -> {{0, 201}, {-0.01, 0.01}}]
, where
List=Table[a[n], {n, 200}] and a[n_]=(-1)^n/n^2
And I need two parallel lines which can be manipulated, so I have written sth like that, but I am not sure if it is correct:
B[z_] = Plot[{z,-z}, {x, 0, 200}, Filling -> {1 -> {2}}]
And I have written such a command to plot A and B and to be able to change values of 'z':
Manipulate[Show[A, B], {z, 0.000001, 0.02}]
But unfortunately, it doesn't work. It drew only a Listplot and skipped B. Where did I make a mistake?
