I am trying to use y* to label a point on the axis of a graph made with DEplot, and am currently unable to.


with(DEtools);
NLC := diff(y(t), t) = k*(Am-y(t));
Am := 20; k := .1;
ivs := [y(0) = 10, y(0) = 30, y(0) = 50];
DEplot(NLC, y(t), t = 0 .. 20, ivs, tickmarks = [default, [20 = y^`*`]], font = [default, default, 30]);

makes y`*` apear as the label, as does the code

tickmarks = [default, [20 = y^`*`]]

wheras if i remove the `` marks I get an error
