>How to perturb the constant f in parametric plots?
> Preferably, I don't press everthing into one line:
> f = 1;
> Now, as f has a certain value, we must block it off, when
defining xy:
Block[{f}, xy = {2 f Sin[t]^2, Sinh[f t] + f Log[t]}]
ParametricPlot[
Evaluate[Block[{f = #}, xy] & /@ {.5, 1, 1.5}], {t, 0, 3}]
Actually got earlier some plot by ParamaeterPlot3D where [ x,y,z=0] =
F(f,t) where f,t, are parameters and chose a vertically up View point,
but this one gives a better flat plot by perturbation rather than taking
special 3D case that I really wanted and thank you for this.
