I tried plotting the function shown below in Mathematica; however the plot showed nothing. Could you help me explain it?
Note that here D' = 1- x.
ClearAll[a, x];
parameters = {0, 0.01, 0.02, 0.05, 0.1};
Plot[(1/((1 - x)*(1 + a/(1 - x)^2))) /@ parameters, {x, 0, 1},
PlotRange -> {{0, 1}, {0, 5}}]
Function[a, (* your function *)] /@ parameters
. $\endgroup$ – J. M.'s ennui♦ Feb 18 '16 at 6:33
